* Remove unused import. * Style: delete excess parentheses. In some of these cases you need to read ahead to see that the paren is not introducing a tuple, for example. * Remove unnecessary list coercions. * Use dict comprehensions now that we can. * Fix bug: used Py2 syntax for except. * Remove unimplemented(): it's not worth it without *-imports. * Remove unused imports. * Fix bugs in diff() and simp(). Add a smoke test. * Fix typos in comments. * Formatting: remove tabs. * Fix some pyflakes complaints. * Fix: there is no utils.caller anymore. * Missing imports. * Typo in comment. * Typo in comment. * Style: address pep8 warnings. * Removed unnecessary list coercions around map (#228) * Notebook for MDPs (#229) * Intro and representation of MDPs in code * Added Image for MDP * Start of CYK parser.
