Inverse maps

[tobydriscoll]

We will want to provide a generalized mechanism for inverse maps. What I propose is to have a boolean flag isInverted in each map object. When that flag is set, a different group of evaluation routines is called that (among other things) invoke inverse mapping functions of the map class. The class can choose to provide them, but they are set to throw errors by default.

Agreed. The isInverted property and default inversion error methods should be implemented in the conformalmap class.
