v1.1.0

• The map now displays trips' trajectories, generate_trajectories() is used to generate them. Warning: this is curently performed at loading - future versions could wait to do this until "show trajectories" is selected on the map view and after desired trip filters are applied
• New data columns for local timestamps, duration in min, distances in mi and km. Some of these and others are later hidden from view in tables/map filter/map popup.
• Add a column visibility button to the tables.
