* init for v3.1 * added coords + bump version * fix filter + added preselected roles * added draw_default_layout * upgraded packages * fixed edge/node labels * fixed enable_circuit_terminations * added filter for unconnected devices * added ignore_cable_type * fixed old settings using a string instead of array * removed distutils * fixed coords check * added coor saving * added doc img * updated docs * bump version * bump version
