0x04 Python for (Nuke) Compers - Lists in Python (our first techyish kinda thing)

Lists are one of those things you hit aaaaaaall the time. Lists of nodes, lists of filepaths, lists everywhere! So it behooves us to introduce two concepts - indexing, and slices.

Both are standard python concepts, so this isn't really nuke specific, but hey, since I've got it open it might be easy enough to handwave here, right?
