…odicity (e.g. using fmod). Oddly, even though FillBoundary with periodicity should impose the same thing, it does not seem to work. Nevertheless this seems reasonable for now, especially since it's unlikely that one will need to define non-periodic rhs in the first place (though this may become an issue later on when looking at hyperelasticity)

This implements several fixes to
Operator::Operator,Operator::Elastic,Solver::Nonlocal::Newton, andSolver::Nonlocal::Linearto enable periodic boundary conditions in elastic solves.This PR resolves
Initial performance check shows a significant boost in efficiency - this is performance for the

FracturePFCZMtest (rightmost point is for this commit)and generally good improvement in elastic solver performance across the board (rightmost points for this commit)
