OK, here's a trick that will let you write

	import Numeric

	Numeric.array(...)

1) Put all the core stuff in Numeric/Core.py.  The Numeric.Core.*
names will be the "official names" for all functions.

2) Provide a Numeric/__init__.py that somehow inserts everything from
Core into Numeric.  I think the shortest hack is the following:

	# This is Numeric/__init__.py
	exec "from Core import *" in __.__dict__

(I haven't tested this but since __ is a shortcut for the parent
module and __init__ is actually a submodule of Numeric, __ in
__init__.py should refer to Numeric itself, so it should work.)
