Setting up Karma with everything else to get new Image() in main.js running (thx to Sebastian Slamanig for helping us out)
Second test: Compass should be an object
Compass constructor available
refactoring tests with a beforeEach to not have to create a new instance of Objects for all tests
furthermore instanciation of compass with 0° as text and 0 degree as rotation
Starting to integrate angles to cardinal directions (starting with converting 0 to north)
Convert special angles (0,45,90,135,...) to cardinal directions
it should still leave normal degrees in there
it should map pixels to degree with a ratio of 4
text of textdiv should be set according to rotated pixels
integrating scroll function with all tests passing
