use pyflakes to identify simple bugs in sympy and fix them
completed by: Matt Habel
mentors: Matthew Rocklin, Vladimir Perić, Stefan Krastanov, Aaron Meurer
Please see http://code.google.com/p/sympy/issues/detail?id=1456 for full information on this task.
Please read https://github.com/sympy/sympy/wiki/gci-2011-landing before completing any tasks for SymPy.
Additional Note(s): Pick a good sized module in SymPy (i.e., one of the subdirectories of the sympy/ directory, but not one of the ones that only has a few files in it). Note that pyflakes complains about many things that really aren't a big deal, so communicate with the mentors about what should be fixed and what does not matter.
