Correlation function crashes on thin box dimensions

If the correlation function analysis modifier is added, if the simulation box is thinner in a dimension than the default FFT grid of 3, Ovito crashes. The GDB output is below. Probably it would work if bin sizes of 0 are rounded up to 1. I will kludge around a bit and see if I can make it act appropriately. In the meantime one could check for nZ == 0 and show an error/warning.

gdb output:
