Add UI tooling for editing muscle curves (e.g. `ForceVelocityCurve`)

[mrrezaie]

Hi,

First of all, thank you so much for developing such an amazing software.

In Properties window, I couldn't find a way to change the properties of muscle curves such as ActiveForceLengthCurve and others in a model with Millard2012EquilibriumMuscle, e.g., Rajagopal. I was wondering if this feature is available.

OC 0.5.8

Thank you.

Hi @mrrezaie , thanks for your praise!

The curves aren't currently edit-able in the UI because it seemed likely that it would require a custom UI (e.g. to select function shape, place spline points, change params, etc.), but it's something that's obviously a UX gap that we need to bridge with a custom UI eventually :wink:

For now, unfortunately, the best that you can do in OSC 0.5.8 (or newer) is to open the osim in OSC and then edit the curves in raw XML (perhaps I should at least provide a raw XML editor in-UI for stuff like this, but that's another feature :-))

I appreciate the time and endeavor you put on this.
