comment and text fixing in ohmpy and modification of the interrogation array to have something actually working for demonstration

installation_file.txt: list package that need to be installed as well the creation of the virtual environment -> must evolves towards a setup.sh file

version testée sur l'ohmpi. Correction de bugs mineurs. Le code fonctionne et ferme les tickets #3 et #5

the append_and_save function has been modified because it is not possible to use the feather binary format on an arm architecture. Move to a simple csv file for saving #5

bugs fixed on prints at the beginning of the file and all parameter values are gathered in one place
