Detailed Description

Basic implementation of a perceiver class.

A Perceiver is, at minimum, the combination of a detector and a tracker or track pointer. It indicates where a "target" is in the image both as a region and as a single point or rigid body frame. If there is a way to meaningfully filter the point/frame, then adding a trackFilter will incorporate that operation.
