Capitalized "MAXIS" where applicable on functions file

NBD.
Added dialog, started work on the PND2

Dialog contains a dynamic dropdown for the scenarios on Excel (it skips
anything labeled "Sheet" (defaults) as well as the "controls" sheet
which I've inserted to allow dropdown lists.
I'm also uploading the sheet. I'm color coding the sections, as well as
the case based vs. person based panels. I think that'll help our users.
