Because I'd like mdds to be product-neutral, general purpose library.
That's the primary motivation on why I started this project, and I
intend to keep it that way.  So, no, I don't want this to be a part of
the repository of one product that uses it.

It is because the repository was a Mercurial repository up until I
converted it to git *only a few days ago*, and I was extremely
uncomfortable using branches with Mercurial.

Now that the repo is git, I can use branches more aggressively.

Sure.  The code mostly affects matrix calculations in formulas.  This
can be either a function that takes in-line formula expressions, or an
expression whose result is an array which spans over multiple cells.

Even when you don't pass or receive matrix data to or from a function,
the code itself may still use the matrix objects, so those functions are
affected as well.  Many statistical functions fall under this category.
