Several fixes to calculations in higher dimensions
Description
Several fixes to calculations in higher dimensions:
- generalize k-point generation
- do not use a Poisson solver for dim > 3.
- generalize output of the dipole and the kick for arbitrary dimensions
Besides, a test is added for dim=4, which was previously not covered by the testsuite.
