Redundant keyword 'mutable' removed in CDL files. In IGESConvGeom_GeomBuilder, unused methods MakeXY() and MakeXYZ() removed. Method StepAP214_AutoDesignGroupAssignment::Init() replicating same method of the base class is removed as it causes CDL extraction error after above (seemingly irrelevant) changes.
