v0.6.9 Adding C3D loader support

Debugged support for C3D loader

v0.6.8 Scaling up multi-trial autoscaling

The multi-trial autoscaling in MarkerFitter now downsamples the input if it's faced with too many trials at once, or too many total frames of input.

v0.6.7 Multi-trial scaling for MarkerFitter

The biomechanics.MarkerFitter object now supports jointly scaling over multiple trials simultaneously, to support that feature in BiomechNet.

v0.6.6 Adding MarkerFitter marker regularization

Bumping to v0.6.6 for MarkerFitter offset regularization

v0.6.5 Supporting rich plots in the GUI

See python/nimblephysics_examples/rich_plots.py for example usage of the new APIs.

v0.6.4 Improvements to MarkerFitter

Improving MarkerFitter:

• Adding confidence bounds to joint estimates
• Supporting joint axis solutions in addition to joint centers
• Exposing more sophisticated GUI methods from C++

v0.6.3.1 Bug fixes

• Fixing a hidden dependency on pybullet for the new PyBullet rendering support. That's now an optional import, so it's possible to use nimblephysics without pybullet.
• Fixing the dimensions of default color arguments to GUIStateMachine to be 4-vecs, to include an alpha channel.

v0.6.3 Customizable contact + OpenSim output features

We've added an alpha API for customizing how Nimble computes contact impulses over a timestep, though we do not yet support differentiating through custom contact functions.

We've also added some OpenSim export functionality, exporting .mot's and an XML file that's readable by OpenSim's scale tool to rescale .osim files.

Adding alpha channel support to web GUI

This contains a number of minor bug fixes, and one breaking change: the web GUI now supports transparency. That means that all the setObjectColor calls to the web GUI will require a vector of length 4, following an RGBA scheme.
