Plugin Support

Credo now supports plugins that run alongside Credo's own analysis. While Credo provided the ability to write custom checks since v0.4.0, users can now access the complete toolset of Credo to create their own commands, require compilation, run external tools and still include the results in Credo's standard report.

Please refer to Credo's README as well as the Credo Demo Plugin for further information on how to get started.
