The menus are just 13 words in RAM that hold pointers to menu structures (i.e.
the 9 math iASAPs, the 3 other math menu pointers, and the custom menu).  The
only space in RAM that is actually _reserved_ for menus is the custom menu
area.  To install your own menus and functions you have to find a space
somewhere in RAM page 0 between $D748+x and $FC00 to squeeze it :-(  The one
good thig is that you don't actually need to put the code for your functions
there.  Just the tokSpell and eos tables there... :-)  I found a nice little
space somewhere around $F300 that is unused by stat and fin (but it is used by
trig ;-)...
