0.4: PERIN Released under Blender Artistic Licence
0.5: WICKES used marker names, fixed 2.45 depricated call
0.6: WICKES creates armature for each subject
0.7: WICKES constrains armature to follow the empties (markers). Verified for shake hands s
0.8: WICKES resolved DEC support issue
0.9: BARTON removed scene name change, whitespace edits. WICKES added IK layers
