Who has never spent time, during a weekend with friends, to calculate how much money each person owes to who ?
This small application offers you to simplify your life.
You enter the names of people, what they paid, and the application will calculate who owes what to whom.

Note that it is possible to group people into groups (such as married). However, it is considered that each person in the group participates like the others (that is to say that if Fred must pay 50 euros in total for the stay, a couple must pay a total of 2 * 50 euros).
So if a person of a married couple should not be accounted (for example because it does not has a salary), then it's name should not be entered in the application.
