Add the possibility to run the same unit tests for different curve representations

[mikebosse]

there should be templated unit tests where you can make a test that is called for each template type in a list. perhaps @HannesSommer or @simonlynen can elaborate

Yes that works pretty good. You can find examples in our code as well.

E.g. https://github.com/ethz-asl/aslam_optimizer/blob/master/aslam_backend_expressions/test/FixedPointNumberTest.cpp

[HannesSommer]

We should really have this one example repository, where one can find tiny examples of our current best practice. That would be great as the canonic place to look for examples.
