def slimpy_base.utils.permute.permute	(		iter_lists,
			restrict = None,
			constructor = None
	)

permute( nested_iterable ) -> permutation_genorator

Takes a nested iterator sequence and returns all of the permutaions

eg. >>> pgen = permute( [[1,2], [3,4] ] ) >>> for permutaion in pgen: >>> print permutaion [1, 3] [1, 4] [2, 3] [2, 4]

>>> pgen = permute( dict( a=[1,2], b=[3] ) ) >>> for permutaion in pgen: >>> print permutaion { 'a':1, 'b':3 } { 'a':2, 'b':3 }

if constructor is not None, the output of each genoration is replaced by permutaion = constructor( permutaion )

if restrict is passed in it may be a callable function that evaluates a permutaion and returns True if the permutation needs to be restricted. if the first egample passing lambda perm: perm[0] == 2 will not generate permutations where permutaion[0] is 2 i.e. only [1, 3] and [1, 4] are generated
