"Solve" with 0 Iterations does not execute properly

[shkodm]

When running some automatically generated from Rtemplate case files I frequently have something like <Solve Iterations="0"/>. This is fine, sometimes I really want to have it. My expectations for this kind of XML element is that it would simply not be executed. (Solving 0 iterations = not solving at all)

What actually happens is probably numerical overflow (I guess) and TCLB is stuck in the infinite loop, burning computational time.

I think the problem lays here: https://github.com/CFD-GO/TCLB/blob/develop/src/Handlers/vHandler.h#L81 I think if should return 0 if everyIter is zero or below. @shkodm can you change it and test?
