A factory class for MatrixBuilder, providing more control over workspace memory.
To allocate workspace manually for a MatrixBuilder, we use the following pattern:;
Because we aren't doing anything special with the workspace, however, this is actually exactly equivalent to just constructing the MatrixBuilder directly, i.e.:
A more interesting case is if we want to use the same workspace for a pair of MatrixBuilders:
