Input testing improvements.  Specifically 'stopstatus' changed to 'flstopstatus', 'flsleep' added to accomodate switching on 'KLres' or 'KLrec' when dependent functions are on but either is off, along with comment, re-asserting 'KLrnumRealz' to be the same as 'numRealz', but only when 'KLWood' is on, and asserting that scattering ratios must be the same within chosen tolerance when 'KLWood' is on.
