v0.6.20 Adding regularization to keep body scales in sync across bodies and between bodies

We've adding regularization to biomechanics.MarkerFitter to keep body scales in sync across bodies and between bodies

v0.6.19 Automate XML to drive OpenSim IK and ID tools

Adding tools to OpenSimParser to automatically generate XML files to drive OpenSim tools for IK and ID.

v0.6.18 Add GRF .mot export support

Adding support to export OpenSim compatible *.mot files for ground reaction forces loaded from *.c3d files.

v0.6.17 Adding TRC Export support

This minor release adds support for OpenSimParser::saveTRC(...)

v0.6.15.1 Minor bugfix for MarkerFitter sort order

In multi-trial scaling we were sorting backwards by joint variability. This is now fixed.

v0.6.15 Making MarkerFitter more robust

Fixing a pair of errors:

• Fix handling for C3D files with NaN marker positions (those observations are now dropped)
• Fix joint center and joint axis solvers, they are now robust to neighboring markers which do not appear at all in the trajectory.

v0.6.14 Performance Improvements for MarkerFitter

An approximately 10x speedup on MarkerFitter.

v0.6.12 Toggle-able layers in the GUI

Adding the ability to group elements in the GUI into "layers", which can be shown or hidden on demand.

v0.6.11 Bugfixes for the C3D loader

This is a very minor release, we're just patching errors in the C3D loader's tag names.

V0.6.10 Intelligent subsampling to scale MarkerFitter

We now subsample trials in MarkerFitter's multi-trial scaling by first sorting by joint variability, then clipping the number of trials.
