Connect this FlowTIn, TOut, TMat to a SinkTIn, TMat, concatenating the processing steps of both. The combine function is used to compose the materialized values of this flow and that Sink into the materialized value of the resulting Sink. It is recommended to use the internally optimized LeftTLeft, TRight(TLeft, TRight) and RightTLeft, TRight(TLeft, TRight) combiners where appropriate instead of manually writing functions that pass through one of the values.

	Func<TMat, TMat2, TMat3> combine
