Added infrastructure for fine-tune score combination... (part-of-the-way commit...not complete)
Merge branch 'montecarlo' of https://github.com/vmohan7/Arimaa into montecarlo
Also a few additions to HardCodedCombiner

AbstractCombiner implements default. Hardcoded agent overrides some values.
Infrastructure in place for more agents. (Perhaps tweak existing hardcoded values?)
