API Documentation

Using [Doxygen](http://www.doxygen.org), the developer facing API has been documented where possible. 

[Doxygen](http://www.doxygen.org) has been setup to look for documented `C` fles within:

+ `src/`; and
+ `test`

When run with the Doxygen tool documentation will be generated within
the directory `doxydoc`. The projects README.markdown file is used at
the documentation's main page.

More information on Doxygen tags and abilities can be found on the
projects website: http://www.doxygen.org
