* Make branches not identical
* Removed temporary file
* 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
- Added a TODO - we need a `parseType()`
* Test cases
- Removed `simple_cast_complex_type.t` as it is wrong, syntax wise
* 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`
- Added `mem.c` external C file to generate the required `mem.o` for linking against `simple_pointer_malloc.t`
* Test cases
- Updated `malloc_test.sh` to look for any `brk()` system calls and fixed its interpreter path
- Fixed module naming; autocomplete now works
Typing
- Added a TODO/NOTE comment
Parser
- Implemented range-based literal type encoding for integer literals
Check
- Switched from directly calling `isNumeric(string)` to our own `isNumericLiteral(string)` to check if a token is a `SymbolType.NUMBER_LITERAL`
Test cases
- Added new test case `simple_literals3.t`
- Made the `data` field `private` and now accessible through a call to `string getLiteralValue()`
UnaryOpInstr
- Use `Value` instead of `Instruction` for unary operator instructions
DGen
- Switched to using `getLiteralValue()` where required due to the aforementioned reasons
- Removed the `varDecWantsConsumeVarAss` as it is not used anymore
- The transformation of the `VariableAssignmentInstr` instruction (which is generated by a corresponding `VariableStdAloneAss` parser node) does not check for `varDecWantsConsumeVarAss` anymore and will directly `transform(varAss.data)` (the embedded `Value` instruction in the `VariableAssignmentInstr`
- If a `VariableDeclaration` instruction has an assignment then we extract the `Value` instruction from it and perform a `transform(Value)` - no longer do we have an intermediary `VariableAssignmentInstr`
Instruction
- `VariableDeclaration` now uses a `Value`-based instruction rather than a `VariableAssignmentInstr` as the embedded `varAssInstr`
Dependency
- The creation of a `StaticVariableDeclaration` DNode for `Variable`-declarations that happen to have assignments will now process such assignments by pooling the expression being assigned (via `expressionPass()` and then make the `VarDecNode` depend on it, therefore removing the intermediary `VariableAssignmentNode` dependency-node
Typechecker/Codegen
- When processing a variable declaration (a `StaticVariableDeclaration` dependency-node) we now pop an instruction which would be directly the `Value`-based instruction that we `need()`'d in the dependency generation (this links up with the changes made to the dependency generation for variable declarations)
- Removed now-completed TODO
Value
- Made the `type` field private and added a comment explaining it
- Implemented `setInstrType(Type)` and `Type getInstrType()`
TypeChecker
- Switched to using `getInstrType()` and `setInstrType()`
DGen
TypeChecker
- Switched to using `getInstrType()`
- Added a note to fix the way we do standalone variable assignments, we should embed them in a way similiar to that of `VariableDeclaration`'s (with assignments enabled)
TypeChecker/Codegen
- Initial work on handling `IntegerLiteral` parser node types added
VariableAssignmentNode
- Push the type onto the typestack and make it the type fo what was popped (relates to the embedded instruction)

- The compilation command now uses the `Compiler` object
- You can now control the symbol mapper used
- You can now set the verbosity level (no-oped currently)
- You can set the output filename
- You can set whether pretty code is to be used or not
- You can set whether or not to generate the entrypoint testing code during emit
- All compilation stages now make use of the `Compiler` object
Compiler
- Added new exception type `CompilerException` complete with a sub-type enum, `CompilerError`
- `getConfig()` will now throw a `CompilerException` when a key is not found, rather than return false (which didn't work under different template types anyways)
- Implemented `hasConfig()` to check for the existence of a key in the configuration sub-system's key-value store
- The `Compiler` object now stores the `Token[] tokens` generated from the call to `doLex()`
- The `Compiler` object now stores the resulting container (`Module`) generated from the call to `doParse()`
- Set default symbol mapping technique to the hashmapper technique
- Implemented `dolex()` for performing tokenization, it will create and store a `Lexer` instance and the produced `Token[] tokens` into the `Compiler` object
- Added `getTokens()` to fetch the tokens generated by `doLex()`
- Implemented `doParse()`, `doTypeCheck()` and `doEmit()` in a similiar fashion to `doLex()`
- Implemented `getMdoule()` to get the container (`Module`) generated by `doParse()`
- Implemented `compile()` which calls `doLex()`, then `doParse()`, then `doTypeCheck()` and finally `doEmit()`
CodeEmitter
- The `CodeEmitter` constructor now takes in an instance of the chosen `SymbolMapper`
DGen
- Switched to the instance of the `mapper` inheited from the `CodeMapper` parent class for any `symbolMap` calls required
- Use the inherited `TypeChecker` instance and not an instance of it provided by `Context`
SymbolMapper
- Reworked this class into an abstract class which must have its children implement a `symbolMap(Entity)` interface, this provides us pluggable mapping techniques
HashMapper
- Moved hashing symbol-mapping technique into `HashMapper`
Lebanese
- Created a kind-of `SymbolMapper` which, unlike `HashMapper`, produces human-redable-yet-valid C symbols (by replacing the `.`'s with `_`'s)
TypeChecker

- Added new symbol types `EXTERN`, `EXTERN_EFUNC` and `EXTERN_EVAR` and related back-mappings
Parser
- `parseFuncDef()` now accepts a default argument (set to `true`) on whether to expect a body for a function or not, in the not case expect a semi-colon - this helps with extern support
- Likewise because `parseFuncDef(bool wantsBody = true)` is called by `parseTypedDeclaration()` we have added same argument to `parseTypedDeclaration(bool wantsBody = true)`
- Ensure we pass the parameter from `parseTypedDeclaration()` into `parseFuncDef(bool)` in function definition case
- Implemented `parseExtern()` for extern support
- `parse()` supports `SymbolType.EXTERN` now
Data

Typechecker
- Implemented `processPseudoEntities(Container)` which loops through the given container and finds all extern statements and then extracts those nodes, parents them to the given container and marks them as external (pseudo-handling support)
- Added first call inside `beginCheck()` to be a call to `processPseudoEntities(modulle)`
Dependency
- Added useless no-op check for `ExternStmt` - it does nothing
DGen
- In `emitFunctionSignature()`, prepend the string `extern ` to the signatur if the given `Function` entity is marked as external (`isExternal()` is true)
