Can be used to settle expenses at the end of a trip or apartment rent fees.

• Create a settlement plan
• Add participants
• Add charges between participants.
• When done, get a summary of debts between participants.

A charge does not have to include all participants in the plan.

A charge should specify the expense distribution over the participants involved (e..g how much each participant should pay).

A relative expense distribution (using prcentage) is not supported.
