Base file w/ node support.

 * Need to implement parseFrame()
Added initial functions for parsing 29.97 to/from frames

* Use String.match to validate string inputs instead of RegExp.match
* Minor style improvements
Working on tests and overrode default toString()

* Using mocha + chai for tests
Timecode constructor throws errors if invalid input
Add grunt watch to run test task
Refactor timecode / task.

* Constructor
  - Timecode(string, number)
  - Timecode(number, number, number, number, number, boolean)

* Timecode.validate()
* toString()
Timecode can be converted to another framerate.
