Initial release

Initial release of MQ 🎉

Includes:

• tools for gathering metadata from the source code: SourceCodeLocation, SourceCodeMeta, SourceCodeContext
• base interface for errors and error handling: TheError
• common errors: Cancelled, InternalInconsistency, StringEncodingFailure, Undefined, Unexpected, Unimplemented, Unreachable
• abstraction over locking: Lock
• placeholders for various of contexts: void, always, noop, unreachable, unimplemented
• replacement for Swift assertions that can be manually controlled i.e. to allow unit test coverage for paths using assertions: runtimeAssert, runtimeAssertionFailure
