0.2 Beta Release Three

This release tidies up the structure of the code and the core changes relate to the module names. The directives module is renamed to csp and the config module is renamed to directives. It is felt these changes make the domain clearer.

Additional Changes:

• The previous directives::build method is now csp::generate.
• Updated README so it provides more accurate setup and usage information.
• Some general code tidy up.

To Do:

• Further improvements to README documentation.
• Add code comments.
• Improve test coverage.
• Continue to improve code abstraction.
