patch names inconsistency
Created by: revoltek
lsm.setPatchPositions(method='wmean') # calculate patch weighted centre for tassellation
patches = lsm.getPatchNames()
lsm.group('facet', facet=mask, root='Dir')
lsm.setPatchPositions(method='mid') # recalculate the patch centre as mid point for imaging
directions = lsm.getPatchPositions()
in these two cases the names in the "patches" variable and the keys in "directions" have different names when more than 10 patches are created. The first has e.g. Dir_1 and the second Dir_01. The best would be to have consistency with naming patches across the code (maybe always without leading 0s).
