Add composite flow rule #137

Closed reverendbedford closed 2 years ago

reverendbedford commented 2 years ago

Add a viscoplastic flow rule that sums the contributions of multiple individual flow rules.

Scalar flow rates are summed, flow directions are weighted by the flow rates and summed, and the sets of internal variables are combined together.
