Added video input and cascade support

The program can now take a stream of images from a folder (the format
provided by KITTI). The cascade is applied and marks found cars with a
simple ellipse.
Implemented master version of main method
Added gitIgnore and gitAttritributes
Cleaned up cascade code

Preparing to move cascade to its own .cpp/.h pairing outside the main
method file.
