Add in compensation for Mx moments due to belt acceleration.

1

Now that we have a stationary V-gait we do not need the inertial compensation with the accelerometers (although it would still help, once we get better accelerometers). But we do...

The tolerance for the missing marker test may be too small.

Loading a compensation trial doesn't really work

1

If you try to load in a compensation trial there are some issues. 1. If "stationary-platform" is false, then the compensation_needed() function returns true, but there is no compensation data...

I don't think I dealt with the axes properly.

The matrix rank of the A matrix is possibly computed twice in the `SimpleControlSolver.solve()` call. Computing the matrix rank of the large A matrices we encounter takes from 30 seconds...

I had this test fail once saying that numpy couldn't assign 160000 values to something like 15692 values produced by a boolean mask. This could possible be a case that...

Figure out what the columns are that in in .Rot[XYZ]

I think these must be HBM outputs that give the segment rotations relative to something.

Add units to the signals

This can be useful for plot scaling. In particular in plot_gains

The label methods in DFlowData should be moved to a class dedicated to that.

Inertial compensation and force reexpression is slow

Needs preallocation here: https://github.com/csu-hmc/Gait-Analysis-Toolkit/blob/master/Octave-Matlab-Codes/Inertial-Compensation/inertial_compensation.m#L145 and here: https://github.com/csu-hmc/Gait-Analysis-Toolkit/blob/master/Octave-Matlab-Codes/Inertial-Compensation/inertial_compensation.m#L145 Stacking arrays in loops might not be the best either: https://github.com/csu-hmc/Gait-Analysis-Toolkit/blob/master/Octave-Matlab-Codes/Inertial-Compensation/inertial_compensation.m#L150j
