part way to removing MatchMols from new ComputeChromeWarp algorithm
More defaults and debugging of new ChromeWarp approach.  Still needs 3D beads properly integrated or removed.
added colordef white to SRstartup
IndexStructure was having some trouble with cell array data, now can pass a flag indicating this is cell array data to process.
Maybe this should actually be default behavior.  Need to run some comparisons repeatedly indexing ProbeData structures (does this produce nested cells?)
Also need to test with mlist structures.
