WIP: Resolve "Implement Ehrenfest ion dynamics coupled to DFTB"
Description
Separate electron and ion dynamics for Ehrenfest propagation with DFTB+. The ion dynamics will be done directly in Octopus, passing the new coordinates to the electron dynamics propagator in DFTB+ at each timestep, which will return the forces to advance the ions.
Checklist
-
I have checked that my code follows the Octopus coding standards -
I have added tests for all the new features added in this request.
Closes #440
