[ADMB Users] survey of memory settings in ADMB

[Ian Taylor]

Thanks for all these Arni,
I'm also looking at the examples models included with ADMB and indeed the
admb-re examples have many more settings than the non-re examples.

I'm also assuming that very few ADMB users have less than 2GB available,
but will try not to require more by default.

Someday we'll follow Dave's suggestion to make the memory allocation
dynamic, but for now some new defaults will hopefully work alright for
average models.
