Micael Oliveira requested to merge refactor_simul_box_output into develop Mar 18, 2021

Description

This introduces two main changes:

Print the information about the space and the lattice in their own section of the log, separate from the simulation box info.
Refactor the write_short_info method of the simulation box. Now this method returns a string and there are two new similar methods for the space and the lattice vectors. All these methods are then used to output the canonicalized xyz files.

News snippet

Refactor the output of the simulation box.
