Started implementing kinect to head-on space conversion,
meaning that a copy of each joint position and orientation is stored with the vertical rotation of the torso cancelled out, which will aid pose matching

Made targetUser and skeleton class members. they can change from frame to frame

Added a lock on the paint function, so that the aforementioned computed values are not accessed before they are ready

Integrated the geomlib vector math library, and added a MathConversion class to transition between NiTE vector and geomlib types

Fixed some null pointer exceptions in the state transition system caused the skeleton being null between an object being picked up and its initial skeleton being made available
added a MathConversion class with static conversion methods
