Convert to Grunt with the Karma testrunner
Travis needs some custom settings for the runner
Another try at Travis
Added Firefox to karma runner, since firefox seems to be failing at the moment
Added special matcher in Jasmine so that rgb() colors are converted to hex before being compared - Firefox converts colors to rgb()...
Added /*global window*/ in line-chart.spec.js so that jslint does not cry
Merge pull request #17 from angular-d3/convert-to-grunt
