Added Example App and Nginx Config

Simple bump here to add in a couple extra files:

• Added a sample app directory containing sample index.php and sample Nginx configuration.

Adding Support for PHP Unit

• Added PHP Unit dependency
• Added testing configuration
• Added first base test file
• Added additional documentation

Initial Release

Initial release with basic stability in place. The following features are supported:

• Route registration
• URI route matching and parameter retrieval
• HTTP Request object with auto body parsing relevant to the verb
• HTTP Response object with ability to override headers and set status codes

There are other nuanced features that have yet to be documented.
