statgen.js

/*   Statgenerator for MUME (VIII)

     Based on VrAK's javascript. Modified by Jahara 10/7/2001 for an added
     age support. Practice percentage support added 4/2/2002 by Jahara from
     Mandor's Stat Generator which happens to also have code by Frn in it.

     - 07/06/2019 updated statgen computeDiff() code from Faine
     - 11/08/2009 cleaned up code, removed filter
     - 10/18/2008 fixed age
     - 10/7/2008 new track % code from Ahura
     - 5/27/2002 Added Stat List
