Create cohesive law file combiner (cohLaw.dat) for parallel processing. This avoids having to broadcast desired information to a head node every output time-step.
Create multiple cohesive law data files when running in parallel, only the right one when not. Only write local information to data files; later combined by ParallelCombiner's combineCohLaw(). It writes N/A to lines with no local data so the combiner can tell which files to draw the info from.

Create multiple stress-theta data files when running in parallel, only the right one when not. Only write local information to data files; later combined by ParallelCombiner's combineSTheta(). It simply appends the data to the end of each time-step list.
