Shared protocol code for client and service to share. Manages the lifetime of Quorum and proposals that needs to be consistent across client and service. It also provides utilities for facilitating summary creation.
A quorum proposal transitions between two states: propose and accept.
A proposal begins in the propose state. The proposal is sent to the server and receives a sequence number which is used to uniquely identify it. Clients within the collaboration window accept the proposal by allowing their reference sequence number to go above the sequence number for the proposal. Once the minimum sequence number goes above the sequence number for the proposal without it is considered accepted.
