+Version History:
+ 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
