Calculate Fréchet distance (similarities) between two geometries

I'm not sure if this should be an option or mode on an existing transformer, or a brand new one.
The Frechet Distance is a measure of similarity between geometries that takes into account the location and ordering of the points along the curves.
Basically an "ish" measurement to see how similar geometries are. Maybe a ChangeDetector with a tolerance of some kind?

We believe this would make sense for the ChangeDetector

This is now in the FME 2019 betas, along with a variety of other updates and revamps to the ChangeDetector/Matcher.
