0.5.0

What's Changed

• Pygmtools is published in JMLR!
• Update download urls for test_dataset.py by @heatingma in #96
• Improved docs & examples
• c_astar modules will be imported only on-demand to avoid #92 for most users
• Backward compatibility broken: pygm.astar now works as a Lawler's QAP solver, just as other pygm.classic_solvers. If you are expecting the old behavior as a specialized GED solver, please use pygm.genn_astar
