ICutter

Returned by CutterApi — the cutter (the negative volume that seats one gem in the metal). Every setter regenerates the cutter in place (same id) and takes literal values: sizes and heights in % of the gem, GemInside in mm. Adds to IGemSetting:

HeightCrown	Height of the crown section
HeightGirdle	Height of the girdle band
