Convert TurkingModule to new-style class
Make code (mostly) PEP-8 compliant
(line-lengths mostly untouced because I don't know how the automatic documentation generator works)
Bugfix. Bad variable name
Replaced variables named cls and str, as they conflict with built in types/funcitons
Replaced path string concatenation with os.path.join.
Minor string formatting fixes.
Pickled list converted to tuple.
unused variables commented for readability.
Replaced classList vs. key_binding check with assert statement
implemented pre/post-processing functions as lambdas
Various performance and readability fixes.
dict.items -> dict.iteritems, since we're only reading through once.
