New version of Matrex

I'm working on a new version of Matrex (2.2).

The purpose of this version is to add functions (formulas).

Matrex has already all functions needed for most users, but with this version I will add functions for specific niches (e.g. financial), functions that are secondary but needed (e.g. fact, log10) and more functions to access the databases.

Now I am preparing a list of all the new functions, as soon as I'm finished I will start the coding. As usual, help is welcome.
