Lists are a way to group cards together without affecting the
stock. Only defined actions will affect it.
Available actions are:
- choose a supplier for all the cards of this list (this doesn't
affect the cards in stock yet).
- add all the cards to the command list (Commands menu),
- transform a list to a deposit,
- receive a parcel and compare it against this list.
We can also export their content in txt, csv or pdf.
