2.0.2
* Add a pointing downward behavior for the Spine model legs when the tracked legs are outside the video frame boundary. The leg positions are more assumptive and less reliable when outside of video frame boundary. The legs should default to pointing downward ( standing position ) to look more natural than flailing legs.
* Start to implement web parallel processing for browsers that support it. Multiple threads might speed up computation tasks.
* Defer 3d graph plotting task to optimize canvas rendering.
* Save 3d plot graph camera location when user rotates the graph. Note that the user can only rotate the graph when the graph is not being updated ("Update 3D Plot" is unchecked).
* Replace the word "body" with "torso" in the animation names of "body_rotate", "body_scale_y", and "body_scale_x". Make these animation names less ambiguous.
