complexFaultRupture does not recognize multiple <complexFaultGeometry> definitions

[raoanirudh]

For an input file such as the one below used in a scenario hazard calculation, only the first segment is used by the engine for the gmf computation. If this is indeed the expected behavior, the engine should throw an error for complexFaultRupture files that contain multiple <complexFaultGeometry> definitions.
