which *Add 2D sym functions and use them*

-This week we attended the GSoC meeting to keep ourselves informed about the progress of all GSoC participants. We finished fixing all long-standing bugs in the updated timeline except *support sortrows* [#362](https://github.com/cbm755/octsympy/issues/362), which was skipped since it was not requested as much as other functions on the list, completing the **past** subproject. More importantly, we continued working on the optional but more urgent *future* subproject. We introduced a helper function to construct 2D sym, which was our way to workaround not having builtin [disjoint union of types](FIXME) in Python. We made use of this function extensively and made considerable progress in getting non-`Expr` out of `Matrix`. For examples, functions such as `@sym/mat_rclist_*`, `@sym/*cat`, `@sym/transpose` `@sym/repmat` now place non-`Expr` in `Array` rather than `Matrix`.
