pymodel and association multiplicity

Hello,

I found what may be a bug in pymodel association multiplicity validation:

if I try:
	multiplicity=[ [ 0, 1 ], [ 0, 2 ] ],
with vanilla Modeling 0.9-pre-17.1 it fails to accept it as a valid association.

patch follows, if I'm correct I'll post it in the patches section :)
