Wrote LigandStats.
Made ECCorrelation keep track of folds.
Deprecated ScanDBForSymmetry.
Fixed definition of m.

Use classification Id, not name.
Don't do 1/10 (that was for debugging). Oops.
Remember cases where we found no EC.
Record SCOP domains where we didn't find ligands.
Moved order statistics into symm.census2.stats.order, and extracted some
subclasses. OrderDecider was renamed to OrderHelper.

Simplified usage for ECFinder, and fixed a bug.
