Added requirements.txt for pip install
Update travis.yml to install stuff via pip, and run nosetests
Add License file - really just a new commit to test travis hook
Add travis build status image to README
Move build image
Use default install command.

This is the default applied by Travis, but this keeps it explicit.
Merge remote-tracking branch 'origin/travis' into travis
Add python 3.2 to travis.yml
Remove u flag from start of strings.

This only used in one test case, but seems to break things under 3.x
sometimes. Not experienced enough with Python to know whether we need
this so trying removing it.
Remove 3.3 from travis for now
Trying to get to the bottom of 3.3 fails
See if we can ignore 3.3
Trying to appease travis
Merge pull request #3 from smulube/travis

Enable travis by adding requirements.txt
