2.1

Improvements and new features:

• The rendering algorithm has been improved in general. (#93)
• Rendering: Lines hitting two corners of the viewbox weren't rendered. (#92)
• Asset loading: Load your Wavefront-OBJ objects exported with blender! (#116)
• New transformation classes:
  • PermutationTransformation (#42)
  • MirrorTransformation (#43)

For developers:

• Debugging: Failed tests don't delete the test-executable any more. (#135)
• Documentation: You don't need LaTeX any more to build documentation (used for generating the math-formulas). Instead MathJax is used to display formulas. (#60)
• Test names are generated from test file names. Now you don't have to provide a test-name explicitly when registering a test. (#123)
