adding in block selector to loadkatfile and parsecommands, so that it only reads in certain blocks. Fixed factorial code in HG_beam

adding xlim/ylim to map plotting function. Fixing issue in test scripts where it wasn't using the correct kat.ini hopefully

adding in more ROMHOM computation and weighting file generations as well as some knm computations utilities. Adding more functions in beam parameter object for plotting parameters

setting defaults in test class more appropriately. Commits are started oldest first now when selecting multiple ones from the list

turns out that some FinesseTestProcess members were static and were shared across multiple processes, like the run time data for the kat files and exception data. This has been initialised properly now

giving owner full read write exec permissions on kat object. Not sure why this is necessary on lnxs machine as the same user has just compiled the kat binary.
