Components of the CIB Generation:

1. Election counter
   Number of elections since the beginning of time

2. Update counter
   Number of updates since the beginning of time

3. Peer counter
   How many nodes was the last update sent to

4. Quorum indicator
   Did we have quorum when the last change was made

To choose the latest generation, the attributes above are checked in order (1 to 4) continuing only if the preceeding comparision was equal.

At some point we may introduce extra sanity checks such as:

• does the update counter comparision agree with the election counter?
