Resolve "AMR regression tests"
This MR adds following tests:
- 4 multi-bunch tests with the ML solver of AMReX
- 4 multi-bunch tests with the AMR_MG solver of Trilinos
- 1 restart test with the ML solver
- 1 restart test with the AMR_MG solver
The multi-bunch tests have the following configurations:
|no. bunches||no. AMR levels|
In each test we compare the beam size, emittance and halo of each individual bunch using the corresponding *.smb file (is a SDDS file).
