	Utilities for 256 color support in terminals.

	Adapted from:
	http://stackoverflow.com/questions/1403353/256-color-terminal-library-for-ruby

	The color palette is indexed as follows:

	0-15: System colors

	Flatten a nested list structure.

	* Works for nested structures of lists, tuples, generators, or any other iterable.
	* Special-cases string types and treats them as non-iterable.
	* Is not limited to the system recursion limit.
	* Yields items from the structure instead of constructing a new list, and can
	work on non-terminating generators.

	This is basically a non-recursive version of the following:

	import re
	from hashlib import md5

	def gfm(text):
	# Extract pre blocks.
	extractions = {}
	def pre_extraction_callback(matchobj):
	digest = md5(matchobj.group(0)).hexdigest()
	extractions[digest] = matchobj.group(0)
	return "{gfm-extraction-%s}" % digest

	"""
	Split the number into its digits.

	>>> digits_of(0)
	[0]
	>>> digits_of(123)
	[1, 2, 3]
	>>> digits_of(0xabc, base=16)
	[10, 11, 12]

	-- centers. Go along the zipper, checking the sizes of palindromes to the left
	-- and right as we go.
