Create a Curvature Display

[jlaframboise]

The curve maker module has some extra features for quantifying it's models, perhaps adding the curvature features (specifically mean, max, and min curvature) to markups to model would be useful to people. Distance and length would also be useful.

Trivial metrics, such as length, surface, number of points, etc. could be added as an Information section within the module GUI (similarly to how it is done in Models module; only computed when the GUI section is open).

Curvature is not needed that commonly, and if needed then a single number is probably not enough (you need to know where the curvature is the highest; maybe color-code the displayed curve). This might be better to do in a separate module.

@jlaframboise meant to add functionality similar to CurveMaker, showing colour-coded segments where blue might be low curvature and red might be high curvature.

Another possibility: I plan to add a feature to resample points along a curve (see #11). So you can do smoothing, up/downsampling, etc... Then those resampled points can be used as an input to CurveMaker (which can display the curvature).

I don't get the impression though that showing curvature would necessarily be difficult to add to this module.

Definitely not, but we need to do something to prevent the module from ever growing.
