The cropping should not be applied at PMC (symmetry) boundaries. Only at physical boundaries like conductors and insulators. |

This modifies the deposition (and field gather), cropping particle orbits at the boundary of the domain for PEC and PMC boundaries. This is a simple way of achieving charge conservation as particles are absorbed at boundaries.
Should this always be done or should a flag be added to turn this feature on?
Only in Villasenor and Buneman current deposition now. Will be extended to Esirkepov.
A second necessary change (with reflective boundaries) is to stop the particle orbits at the boundary so that in the next time step, the particles start at the boundary.
