faMesh does not have own registry
Functionality to add/problem to solve
faMesh does not have its own objectRegistry but uses the polyMesh one. This means e.g. that its data() conflicts with that of a fvMesh.
What does success look like, and how can we measure that?
Successfully run any finiteArea case with
DebugSwitches
{
regIOobject 2;
}
(this debugswitch will trigger aborting upon double registration)
