Crate hopr_ticket_manager 

Implements complete logic of ticket management in the HOPR protocol.

There are two major parts in the architecture of the ticket management:

• HoprTicketManager is responsible for managing the incoming ticket queues and ticket redemption.
• HoprTicketFactory is responsible for managing outgoing ticket indices and creating outgoing tickets.

Usually, they are created together via HoprTicketManager::new_with_factory.

See the HoprTicketManager and HoprTicketFactory documentation for complete details.
