A * B * C + D * E should compile #52

Right now this is Chain + Chain. Evaluating that expression is wasteful because both sides will need to be evaluated.

Instead changes the types such that the expression becomes Chain + Product<SubMat, SubMat>, then we can always eval the LHS, and use that allocation to store the operation.
