PiCentral Vision Driver Application

[camilne]

Resolves #257.

Creates an executable that connects to the BeagleBone over a TCP connection using the tacopie library. This executable includes the vision library. Also has the structure to pass a camera or url to a video feed as command line arguments. Has the ability to accept a template image.

This includes temporary Capture and GateDetector classes as a representation of how the vision library will be incorporated when it is working.
