major overhaul to allow specification of GA params via input file; this may have broken things (some dynamix runs hang) and I have yet to make the input file/parser
corrected initialization of genomes, have better output with pid and MPI rank
changed nomenclature of objective functions
added more parameters to GAParams class
moved Params out of GAParams, made gp a global variable because I cannot modify (easily) the galib objective function calls...
gp needs to be initialized for all MPI processes, otherwise buffer may be wrong size
