A pure-python list shifter/wrapper

Project description

A pure-python list-shifter/wrapper. Shifts/Wraps an iterable left or right by any amount (modulo to the length of iterable). Can optionally shift the iterable in-place. Create a shifty instance to add these convenience methods to the default list implementation if you prefer.

Why slice when you can shift ‘like-a-boss’ ?!
