Add support for basic matrix and vector operations

[asi329vdu8o]

I have noticed that evaluating matrix/vector operations like multiplication or addition in a Mathlive mathfield does not work out of the box and I did not find anything about it on the documentation either.
For example doing '(1,2,3)+(3,5,6)' will evaluate to '(1,2,3)+(3,5,6)' instead of '(4,7,9)', same goes when using matrix syntax using the 'Add matrix' option, so m1 + m2 = m1 + m2.

I'm not sure if there is currently any way of doing these operations directly from a LaTeX input, if there is please tell me.

Otherwise it would be great if you could add it.
