Added R wrapper for get_stats_grid
Tested + verified get_stats_grid
Get stats grid has been updated + tested for binary and poisson input data (as described over skype). Both types seem to be returning responsibly - no obvious errors. Modified the runner method (noKernelMultiGilStats in C) to pass maxInfest also to get_stats_grid.
