Syntax
template<typename InputIteratorT>
class TPairExpandIterator
Remarks
Wrapper around existing integer iterator that returns either 0, 1, or 2 integers for each value that the original iterator returns.
This is specifically used by FDynamicMesh3::VtxTrianglesItr, where for each edge around a vertex, between 0 and 2 triangles need to be returned.
This is done via the PairExpandFunctionT TFunction, which returns a FIndex2i for a given integer. This pair must be either (a,invalid), (a, b), or (invalid, invalid), where invalid is integer < 0
