Veto

A trait representing an object that has an objection to a particular action. This objection is manifested through a human readable vetoMessage which would generally also be displayed in the GUI when calling tryResolveVeto.

For example, if trying to close a window that is in dirty state, calling tryResolveVeto will display the veto message in a dialog to the user, and the user can confirm the closure, which would result in a true return value, or abort the closure, which would result in a false return type.

Attempts to resolve the veto condition by consulting the user.
returns
successful future if the situation is resolved, e.g. the user agrees to proceed with the operation. failed future if the veto is upheld, and the caller should abort the operation.
