ImplicitFunction: expand for MD needs, integrate with MDEventWorkspace

[Janik Zikovsky]

I need a robust way to determine whether a MDBox has any intersection with an ImplicitFunction; I can focus on Box and Plane functions at first.

Simply checking whether the center and/or any of the corners are in the function is insufficient because the box might be LARGER than the width of the plane and so not actually have any of its corners in it.

Calculating the intersection between the edges of the MDBox and the Plane might do it.

Support for non-aligned planes/boxes would be good; maybe do this from the start so there's less to support.

NOTE to myself: A box and a plane with width = pretty much the same thing.

Good test coverage. Wrapped now by PlaneImplicitFunction and BoxImplicitFunction, and existing test suite reused there to verify proper workings.
