MetaProcessor
- Extract the `CompilerConfiguration` via the `TypeChecker`'s `getCompiler()`

- Implemented `getConcreteType(string typeAlias)` which transforms the type alias into its
concrete type; this method incorporates defensive programming in that it will only apply the transformation IF
the provided type alias is infact a type alias, otherwise it performs an identity transformation
and returns the "alias" untouched.

* AST nodes
- `FunctionCall` now has the ability to be marked as statement-level by calling `makeStatementLevel()`, this can then be queried later via `isStatementLevelFuncCall()`
* Parser
- Statement-level function calls were never actually returned, resulting in `null` being returned by `parseName()` - this has now been fixed.
- Along with this we now "mark" this `FunctionCall` AST node as statement-level when it occurs in `parseName()`
* Instruction
- Allow `FuncCallInstr` to be makred as statement-level and queired much in the same manner as its corresponding AST-node/parser-node `FunctionCall`

* Builtins
- `getBuiltInType(TypeChecker, string)` will now return a `Pointer` object for arrays of which the type was `<componentType>[]` (non-stack bound) as effectively they are pointers with a different syntax -doing it here means that it is transparent and typechecking, code gen and emit will just see a pointer type which makes life a lot easier
* Builtins

* Test cases
- Updated test case `simple_arrays2.t` to show case bug sub-issue 3 in issue #81

Dependency
- Temporarily enabled the `StackArray` type in dependency processing for `VariableDeclarations` such that we can continue through the pipeline
Test cases
- Updated `simple_arrays.t` to test stack-based array types
* Tets cases
- Added new test case for testing (later) multi-dimensional stack-arrays
* Parser
- Working on adding array index assignment support
Test cases
- Added test case to test array assignments with
* Parser
- We can now detect when infact we are doing an array-indexed assignment and when not, we then flip` arrayIndexing` to `true` if that is the case and ensure that `=` SymbolType.ASSIGN is not triggering the varaible-declaration-with-assignment but rather eters a different branch based on this boolean
- Set the identifier being assigned to (in the array indexing case) to the `type` with the `[]...` stripped
Notes
- Added a TODO file `wip.txt` with notes about what is to be done for adding full array support
* Parser
- Handle the case whereby `SymbolType.ASSIGN` or `SymbolType.IDENT_TYPE` is not found by throwing an error

* Parser
- Added right-hand side expression parsing for array assignments

Data
- Implemeneted `ArrayAssignment` which is to be used for assigning into arrays
* Instruction
- Added new instruction for indexing into arrays, a new `Value`-type instruction called `ArrayIndexInstruction`
* DGen
- Handle `ArrayIndexInstruction` which is for whenever you index into a point-based array (an expression like `myArray[i]` is now being supported in emit (first steps))
* Instructions
- Added a new instruction type, `StackArrayINdexInstruction`, which is used to know when we are indexing into a stack-based array rather than a pointer-based array (just to be able to disambiguate between the two)
- Added a work-in-progress type `StackArrayIndexAssignmentInstruction` which will be used for assigning to stack arrays at a given index
* Instructions
- Added implementation for `StackArrayIndexAssignmentInstruction` which represents the assignment of some `Value` instruction to a stack-based array (indicated by the `arrayName` string field) at the index indicated by the provided `Value` instruction

- Added a stub emitter for `ArrayIndexInstruction` (pointer-based array indexing)
- Added a stub emitter for `StackArrayINdexInstruction` (stack-array based array indexing)
* INstructions
- Added `getArrayName()`, `getIndexInstr()` and `getAssignedValue()` to `StackArrayIndexAssignmentInstruction`
* Instructions
- Added `ArrayIndexAssignmentInstruction` which is intended to be used for when one wants to assign into a pointer-based array
- It embeds a `Value` instruction which is what is to be assigned and then an `ArrayIndexInstruction` representing the base of the poiinter-based array (base address) coupled with an "index" (offset)
- Added a `toString()` override for `StackArrayIndexAssignmentInstruction`
* Test cases
- Added `complex_stack_arrays1.t`
- This tests a stack array of a fixed size of `int[]` (basically `int*`) and assigneing into it
* Test cases
- Added `simple_arrays4.t` which makes an `int[]` (which is an `int*`) and then assignes into it at `i` whilst referring to itself at `i` and doing a binary operation
* Test cases
- Added `simple_stack_arrays2.t` which tests a stack array of a fixed size and then assigns into it a value
* Test cases
- Added `simple_stack_arrays4.t` which just tests assigning to a stack array of a fixed size BUT referring to said stack array itself as part of the assignment expression
* DGen

- This will then set the context of the parser-node to the current context
- The index expression will be depended upon
- The indexed expression (the entity being indexed) will be depended upon
---
- Added dependency generation for `ArrayAssignment`
- The `ArrayAssignment` parser node will be pooled
- The `ArrayAssignment` will have its context set to the current context
- The assigned expression will be depended upon
- The entity being indexed will be depended upon
- The index expression will be depended upon

- Disabled the intentional `assert(false)` when handling array assignments
- Assign the generated `ArrayAssignment` to the `generated` variable
- Updated `parseExtern()` to cast to `TypedEntity` to ensure that the `Statement` returned is of that sub-type (added an assertion to then check this fact)
* Typechecker/Codegen
- Implemented `isStackArray(Value)` which checks if the given `Value` instruction is a `FetchValueVar`, then extracts the `Variable` being referred to in said instruction and checks if its declared type is that of `StackArray`
- Implemented code generation for `ArrayAssignment`
- Implemented code generation for `ArrayIndex`
* Test cases
- WIP: Added `simple_stack_array_coerce.t` as we want to add coercion for this now
* Typecheck
- Added rudimentary check for checking if an argument is a stack array, and if the parameter (to a function call) is a pointer and if so then returns whether they have matching component types in a new function named `canCoerceStackArray(Type, Type)`
* Typecheck
- Fixed `canCoerceStackArray(Type, Type)` to actually coerce the first type first into a pointer type (coercing the stack array's component type to `<compType>*`) and THEN apply the `isSameType(Type, Type)` check
* Typecheck
- Hoisted up `canCoerceStackArray(Type, Type)` to the class-level of `TypeChecker`
- Removed debug prints from `canCoerceStackArray(Type, Type)`
- Added a TODO where the check should be done in the `FunctionCall` branch of the `DNode` processor
* TypeChecker
- Added a seperate check for function call `DNode` processing which now checks if we can coerce the stack-array-based argument to the pointer-based type parameter
Notes
- Emit now fails as we haven't implement an emit for this case, so we need to do that.
- Also, should we change the type of what is being passed in - perhaps that actually makes sense here - we haven't fully coerced it actually
* TypeChecker
- Updated `canCoerceStackArray(Type, Type)` to now take in `canCoerceStackArray(Type, Type, ref Type)` to set the newly created coerced type
- Fixed bug whereby if the coercion succeeded we didn't actually add to the list of evaluation-instructions in the `FuncCallInstr` object, hence there would be a `null` Instruction object appearing in the code emit phase.
- Added some NOTEs which we can clean up this code using
* TypeChecker
- Cleaned up commented-out code
* Added CI/CD test for 'simple_stack_array_coerce.t'

* Added CI/CD semantic tests (WIP) for 'simple_arrays2.t' and 'simple_arrays4.t'
* Added CI/CD semantic tests (WIP) for 'simple_arrays2.t' and 'simple_arrays4.t'
* Added CI/CD semantic tests (WIP) for 'simple_arrays2.t' and 'simple_arrays4.t'
* Fixed filepath for test 'simple_arrays.t'
* Fixed typechecking tests for arrays
* DGen
- Added instrumentation for `simple_stack_array_coerce.t`
Test cases
- Updated `simple_stack_array_coerce.t` to update the array passed in a manner such that we can sum the two elements later, return it and assert to ensure it is set correctly
* Parser
- Had to ensure the old identifier code was removed too, was too early; therefore this now-dead code was removed
* Test cases
- Added this test (even though it is a bad test, the syntax ie wrong)
* Test cases
- Update `simple_stack_arrsys4.t` to return an `int` such that we can verify it works.
- Also added more tests to it.
DGen
- Added semantic test code generation for `simple_stack_arrays4.t`
CI
- Re-organised tests for semantics in emit for arrays into those "Which have semantic tests" and "those which don't (yet)"
- Added semantic/emit test for `simple_stack_arrays4.t`
* Test cases

* Test cases
- Updated `complex_stack_arrays1.t`
* Test cases

* Test cases
- Added test case `complex_stack_array_coerce.t`

* Typecheck
- Added `attemptPointerAriehmeticCoercion(Value, Value)`
* Typechecker
- Moved `attemptPointerAriehmeticCoercion(Value, Value)` to class-level and made privately accessible
* Test cases
- Added pointer arithmetic in the form of `*(ptr+0)` to `simple_pointer.t` to start testing it out
* Typechecker
- When handling `BinaryOperatorExpression` call `attemptPointerAriehmeticCoercion(Value, Value)` with both `(vLhsInstr, vRhsInstr)` before we call `vLhsInstr.getInstrType()` and `vRhsInstr.getInstrType()` before `isSameType(vLhsType, vRhsType)`. By doing so we attempt to coerce the types of both instructions if one is a pointer and another is an integer, else do nothing
* DGen
- When emitting for `PointerDereferenceAssignmentInstruction` we didn't wrap `<expr>` with `()`. So instead of `*(<expre>)` we got `*<expr>` which doesn't work if you're doing pointer arithmetic
* Test cases
- Added `simple_pointer_cast.t` to test casting (currently broken parsing-wise)
DGen
- Added a todo for semantic tests for the `simple_pointer_cast.t` test case
* Parser

* Test cases
- Removed coercion usage, I am only testing the casting here (explicit)
* Test cases
- Removed `simple_pointer_cast.t` and replace it with `simple_pointer_cast_le.t` which casts the integer pointer to a byte pointer and sets the lowest significant byte (little endian hence at base of integer) to `2+2`
DGen
- Added semantic test for `simple_pointer_cast_le.t`
* Test cases
- Update `simple_pointer_cast_le.t` to do some pointer airthmetic at the byte-level of the 32-bit integer
DGen
- Updated the semantic test code generation for `simple_pointer_cast_le.t` to check for new values
* Added 'simple_pointer_cast_le.t' to Emit tests
* TypeChecker
- Update `isSameType(Type t1, Type t2)` to now handle pointers explicitly and in a recursive manner based on their referred types
- This check occurs before the `Integer` type check therefore following the rule of most specific types to least
* Test cases
- Added new test case `simple_pointer_malloc.t`
- Added semantic code test generation for `simple_pointer_malloc.t`
- Added `malloc_test.sh` to compile and generate `mem.o` from `mem.c` to link it then with `simple_pointer_malloc.t`

* Test cases
- Updated `malloc_test.sh` to look for any `brk()` system calls and fixed its interpreter path
* Praser
- Added TODO in `parseFuncDef(bool)` explaining where we should place the type deriving code
* Parser
- Attempt "Solution 1" of `#111`

* Parser
- In `parseFuncDef()` we have removed commented out code which was, as mentioned in the last commit, incorrect code that expected old type code for pointer handling
* d
* Removed placeholder
* Parser
- Added a new default parameter to `parseTypedDeclaration()` which is `onlyType=false`. If one sets this to `true` then we will parse the type till the identifier (what would be it) but stopping on the identifier and returning a bogus `TypedEntity` with a fake name string but with the type string intact
- `parseCast()` now uses `parseTypedDeclaration(onlyType=true)` - this should help us when we want to cast for arrays or pointers (where all that logic is in `parseTypedDeclaration()`).
Test cases
- Added a complex `cast(<expr>)` with a pointer - this should work in upstream `pointers` branch
- File name is `simple_cast_complex_type.t`
