Constraint fix, apply constraints to wrists.
Merge branch 'master' of https://github.com/worklist/hifi
Back to the cyclic coordinate descent algorithm (easier to apply joint
constraints); Leap hands relative to eyes.
Alignment to pull elbows towards ground.
Orient the Leap hands relative to the body, not the head.
Order of update fix.
Only rotate if we have at least three active fingers.
Finger IK, take two.
Scratch that; didn't work.
Merge pull request #1250 from ey6es/master

Back to CCR for IK (with rotational alignment to replace "gravity"), read/apply constraints correctly, Leap tweaks.
