@lkdvos is it alright with you if I merge this? It will probably cause conflicts for #79 but I think they shouldn't be too hard to deal with and I need to merge this in order to update other packages to TensorAlgebra v0.6.

[lkdvos]

Yes, no problem! apologies for the slow reply, I got slightly sidetracked on this. I'll deal with the merge, I agree it shouldn't be too hard.

Thanks. While upgrading some other packages like KroneckerArrays.jl I realized there were a few things off with the new matricization interface so I'm tweaking it now, which might affect this PR (but after that is fixed I'll merge this).
