Refactored persistence to be broken up rather than using npm's bundled dependencies feature.
Revised security service documentation to produce better yui documentation.
Added yuidoc grunt task to produce and clean documentation on build.
Dropped markdown pdf generator task running during build as it no longer produces good output since the markdown file was broken down into multiple.
Updated yuidoc path and added it to the .gitignore file.
Updated mock persistence service to be inline with the new refactored structure.
Also dropping outdated unit tests from the mongo module.
