Class OCCTSelect

Choosing faces and edges of OpenCascade shapes by what they are, where they lie and how they meet, rather than by an index that shifts whenever the model changes. faces and edges return index lists in the getters' numbering, which fillets, chamfers and the getters take as they are, and which the selectors narrow further through their indexes input. A choice of nothing stays empty through the selectors, but fillets.filletEdges and fillets.chamferEdges read an empty indexes as every edge, and hand out radiusList and distanceList in the getters' order.
