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.
