Rename Python template files, otherwise distutils will try to compile them during building
...and of course also adapt setup.py so that it copies ".py_" instead of ".py" templates
Fix an incorrect reference in the docs
Change 'active' flag to 'unless-refractory' and 'is_active' to 'not_refractory'
Implement new refractoriness system
Add missing newlines after "not_refractory = ..."
Make sure to handle semicolon-separated statements correctly
Fix Exponential Euler integration for equations with only constant terms
Initialize the not_refractory parameter with True
Fix some issues surrounding the use of more complex expressions
(cherry-picked from synapses branch)
Deal with boolean variables correctly by wrapping them in "bool(...)" -- we have to find a more convenient way to handle this
Add tests for refractoriness
One more test for refractoriness and fix get_identifiers to not return keywords
Add some documentation for the new refractoriness mechanism
Merge pull request #66 from brian-team/refractoriness_final

Finalize the refractoriness mechanism
Fixed refractory flag in I-F_curve_LIF
Have a saner default for the refractory keyword (0 refractoriness instead of infinite refractoriness), add a warning in case of a missing refractory keyword when the unless-refractory flag was used
Correct the LIF example to use the correct new refractoriness syntax.
Closes #71
Fix typos in the C version of the bool function
Merge remote-tracking branch 'origin/master' into synapses
