- Disabled normal `get()`-based tests for now (whilst I test the timeout-based ones)
- Added unit test to test timeout-based `get(Duration)`
CoapRequestFuture
- Added documentation for `get(Duration)`
- Fixed bug whereby the `Mutex` was NOT unlock after a failed `wait(Duration)` (a timedout one)
- Removed the `Socket` instance
- `init()` now calls `begin()` on the messaging layer and no longer creates a new `Socket` itself
- `close()` now just calls `close()` on the messaging layer
- `transmitRequest(CoapRequest)` now calls `send(CoapPacket)` on the messaging layer instead of via a socket's `send(ubyte[])`
CoapMessagingLayer
- Added a `running` flag
- Added `begin()` which sets the running flag (ours) to `true`, it then creates and opens a `Socket` and then starts the reading loop
- Added `send(CoapPacket)` whcih wire-encoded the packet and then sends it over our `Socket`
- Added `close()` which sets the running flag to false, shutsdown the `Socket` (unblocking any blocking receives) and then closes the `Socket` (releasing the bound datagram port)
- Removed references to the `CoapClient`'s now-non-existent `Socket`
- Removed `getAndReset()`, replaced it with `hasTimedOut(Duration)`
CoapClient
- The `watch()` now uses `CoapRequest`'s new `hasTimedOut(Duration)` method
- Added a `Condition` variable for the `requestsLock` mutex
- Added `transmitRequest(CoapRequest request)` which will take in the `CoapRequest`, yank the `CoapPacket` from it, encode it, send it over the underlying transport and then start the request's timer
- Added some code for a future "watcher" routine
CoapRequest
- Added a `StopWatch` timer which does not auto start
- Added `startTime()` which starts the timer
- Added `getAndReset()` which gets the elapsed time and resets it
- Now takes in the original request packet, `CoapPacket` instead of the token
- Added `getToken()` to fetch the token (for matching purposes)
- Added `getRequestPacket()` to obtain the original request
CoapClient
- Use `getToken()`
- Pass the `CoapPacket` in rather
- Added new constructor `this(string host, ushort port)`
-This constructor provided name resolution on the host part.
Client (unit tests)
- Updated unit test to use the new `CoapClient` name-resolution-based constructor
