Detailed Description

Calving models based on crevase depth computed from viscous stress CrevasseCalvingModel implements the methods common to all of these, and requires its subclasses to compute a remnnat given the stress. The remnant could be the remaining thickness of ice remnant = (thickness - crevasse depth)/thickness but could be any quantity where remnant = 0 indiciates full fracture and remnant > 0 is a partial fracture.
