[Matrix-SIG] Proposal: Move array_map and array_set into NumPy core

[Travis Oliphant]

There are several useful utilities that would work nicely in the NumPy
core.  The first is the array_set function from gist, which allows setting
elements of an array using the index. The second is an array_map method
which I recently wrote and placed in SpecialFunctions (cepes) that allows
"vectorizing" an arbitrary Python function -- i.e. it is a map that
implements the universal function broadcasting rules.

Comments?
