- There is now GaiaGraphicsTestCase which is a subclass of GaiaTestCase and ImageCompareTestCaseMixin  (had to modify runtest.py to add new mixins i created)
- mixins are added to the mixins folder
most of the parameters are now taken from the gaiatest parameter
- GaiaGraphicsTestCase takes case of boilerplate code and imagecompare_util
- Checked against pep8 checker tool
