Changes

• Broke out public/private functions into separate folders (this cleans things up a bit, makes it easy to see/track changes to individual files/functions
• Added pester tests/integrated with appveyor for automated testing
• Bundled the yaml dll with the module, removing the need for internet access upon first run (should resolve issue #4 )
• Updated documentation to reflect the changes, kept the legacy adoc and replaced with markdown doc
• Added MIT license (This should resolve Issue #2 )
• Added a cool, custom logo
