Release 0.2.0

Lots of documentation and inline comments have been added in; limited ability to parse different property value types has been added in; a colours module has been added - in future this will contain functions for converting between different colour spaces.

Release 0.1.0

A basic version of the code is now working. The code is able to parse the basic syntax of Morphe, though doesn't yet identify different types of property value. It also doesn't give useful syntax error messages.
