spirol 1.0.7

A pure-python non-repeating outside-in spiral iterator-generator for 2D arrays

# README #

Take any two dimensional list like object that supports indexing as input and output a circular clockwise shrinking
spiral of elements from the input beginning at the top left most corner (ie: input[0][0]) until all the input is
exhausted.

This will work on lists of any size in either dimension.

>>> a = spirol([[1,2,3], [4,5,6], [7,8,9]], (3, 3))

>>> a
spirol(3, 3, clockwise from tl)

>>> [i for i in a]
[1, 2, 3, 6, 9, 8, 7, 4, 5]

>>> print(a)
