Found a possible bug in ypnos. Waiting to hear from Dominic about it.
CSV are not versioned.
Using mirror instead of clamp boundaries for run.
Have implemented the avg function in original ypnos. The intent was to use it
in the tests but the results turn out different due to not being able to
construct a mirror boundary that works properly. It is now being used in the
benchmark (as it doesn't really matter if the boundary is treated differently).
Shouldn't have versioned these files.
fixed a bug in the boundary generator
added size combiantor
Merged in Dominic's fix for the boundary problem.
