Began adding support for Python 3.3. Unit tests that do not require a simulator now pass with both 2.7 and 3.3.
Added `utility` module to setup.py
plotting.py modified to make it accept numpy arrays
test_randomness.py added in examples
comments added
wording changes to make it PEP8 compliant. matrix -> array in plotting. First changes in test_randomness.py
test_randomness renamed connections. Writing connections.py to allow the testing of several connectors
pep8 changes
Loop over connector types implemented in examples/connections.py. I loop over all connector types, except the SmallWorldConnector, the CSAConnector, the FixedNumberPostConnector.
Merge branch 'master' into numpy_array_plotting
Temporarily commented out new NEST connector classes, while I try to get all the tests passing with NEST 2.4
Merge pull request #315 from JoelChavas/numpy_array_plotting

plotting.py modified to make it accept numpy arrays
Small fix to work around a bug with handling unicode names in NEST 2.4.1
unittests backend testing: first register mechanism tested with mock backends on test_population.py
more generic backend unittests. test_nest and test_neuron added
add nose configuration file to separate unittests and unittests/backends testing when using nosetests
add backends/test_brian.py
add include_only mechanism. Put the function checking gor test inclusion in glob_import
Minor reshuffling in NEST backend
code cleaning. alias_cell_types made more general
