Add travelers to a trip

Add companions so you can split costs and track who owes what

1. Step 1: To add travelers at any stage, go to a trip's settings and scroll to the 'Traveling with' section. Add as many travelers as you want.
2. Step 2: Once a trip has at least one other traveler, when adding or editing expenses you'll see the option to split expenses or mark expenses as being owed.
3. Step 3: When a trip has split expenses, a summary of what you split with whom will appear in a dedicated table at the bottom of the trip list.
