LGTM - thanks for the patch everybody. During the merge I consolidated the builtin function names, added the missing dml documentation, moved the strategy selection into the dml-bodied builtin function, and vectorized a number of loops in the dml-bodied builtin function, and fixed the check for identity matrices.
