Added major merger support options for finding trees
Now highlights major mergers
UI and code cleanup and merger of precomputed with full compute

myriaMergerTreePrecomputed has been cleaned up, both in code and the
UI.  myriaMergerTreeFullCompute can be removed now, and
myriaMergerTreePrecomputed should be renamed to myriaMergerTree since
it now contains both functionality.
