Sample Code: Create Animation with Matrix in HPS sandbox

This is a sample code to create an animation from matrices. Use HPS::MatrixKit::Decompose to get a translation and rotation from that matrix, then make a keyframe for each of those values that occur at tick X and append them to their respective channel's keyframe arrays.
