This will update the package to the new API of preCICE v1 and will drop support for preCICE v2.
- preCICE has many new checks for sensible data. Especially small values (as the velocities in the tests) are a problem. That makes it impossible for me to reproduce the results obtained by preCICE 1.6.X
Check how if there is a way to force preCICE to accept smaller values
If it is not possible to reproduce old results, we need to adapt the test cases/reference solutions.
Closes #15 (closed)
