setup — store relative joint position training data

[ludimation]

This training data should reside separately from the current "Absolute Position" training data.

• debug relative joint positions (store in separate data set so we can compare for which works best)
  • place relative to either joinPos - centerPos, or jointPos - torso components
  • see if there's a way to figure out where the ground is so that overall height of the pose relative to the height of the user can be used in the training data set
  • normalize data? (might be something that's already being done by GRT)

Done. This seems to work pretty well. Still have to test this method vs. absolute positioning (could be done through GUI radial button switch at some point).
