ReMake of Data Collecting Project

---- Lost Code, probably rewritten somehow :)

Until now :
	- written code for faceTrackingViewer *
Further :
	- rebuild interface (MainWindow Class)
	- add button for "Collect Data"
	- Optional: Dropdown for type of emotion
	- refactor writing (opens and closes on each frame read)

* code for saving data, code for 3 frame trigger.
Merge branch 'master' of https://github.com/danielmihai/face-tracking
