Description
This has been talked about, but I can't find where, so I'm opening a new issue. I'd like a few extra features for Inverse that would be nice--
Inverse(StridedMatrix pts): when the map is square, why bother with the fixed part of the matrix. This can be implemented simply as just calling the normalInversefunction with an empty view as the prefix, and we can always make this more efficient when we get to itInverse(StridedVector x1, StridedMatrix pts): When the map is rectangular and we want the conditional inverse of a bunch of points with respect to the same prefix. This would make implementing aFixedMap(See #245 ) a little easier.

Research direction
Start by locating the existing Inverse overloads and review how the square-map and conditional-inverse cases are currently represented. Use the proposed Inverse(StridedMatrix pts) and Inverse(StridedVector x1, StridedMatrix pts) signatures, along with FixedMap in issue #245, to define the expected behavior and add coverage for both cases.
