I ran into this line of code when searching for functions. Not sure if it's a bug or this function is still being used. https://github.com/keenon/nimblephysics/blob/99cbc86ed34aca4b53f3670c771779fbd2487ca4/dart/biomechanics/DynamicsFitter.cpp#L201

Error if the unit of CoP is mm in grf.mot

[report_error.zip](https://github.com/keenon/nimblephysics/files/11127859/report_error.zip) I'm not sure what the "forcePlates.corners" is. If it's CoP, then the bug might be in...

skel returned by readSkel function does not have body scales

[readSkel function](https://github.com/keenon/nimblephysics/blob/b20d7b571b895b51e401f077a66bd44d7ebf6557/dart/biomechanics/SubjectOnDisk.cpp#L631) sets gravity vector. However, it does not set body scales, which are needed for forward kinematics and my loss functions. Based on [Nimble wiki](https://nimblephysics.org/docs/working-with-addbiomechanics-data.html#nimblephysics.biomechanics.SubjectOnDisk.readSkel), readSkel is used for...
