Commit file needed for generator branch.
Merge branch 'master' into gens

Conflicts:
	include.tex
introduce itertools

Introduce the itertools library from the Python Standard Library.  We
should probably add a problem or two that use the iterators from
itertools.
update contributors

Add all known contributors to date.
update explanation of generators

Describe generators a little more in detail.  Removed a less than useful
problem.
added another generator problem

Implemented a problem idea suggested by Jason Grout.  Made a gray code
generator that is much faster and more general.
huge speedup by using Python 2.7 feature

Used a feature of Python 2.7 to find the highest bit set of an integer.
remove unused import

math.log is not used anywhere.

Also added some whitespace by suggestion of pep8
separate the two dynamic programming labs

These should each have their own folder
allow makelab to handle references

makelab needs to run latex multiple times in the case that there are
references.  Otherwise, we get ugly ??? instead of the correct labels.

Also removed redundant command in template.tex that caused errors with
makelab.py
corrections and beautifying Value Function lab

Removed un-needed numbering in equations.  Labeled problems and lists
properly.
corrections to Policy Function lab

Added Policy Function Iteration lab to Vol2.tex.  Cleaned up and removed
un-needed equation numbers and fixed labels and references.
found another way to cite Brualdi's book

Need a way to cite books that are referenced in the lab.  Right now, we
are going to do footnote citations, but it would be nice to have a
References section at the end of each lab.
