-/**
- * An implementation of the Berkeley Algorithm for clock synchronization.
- * On view changes and otherwise at a configurable interval this protocol
- * sends a request for the current millisecond clock to all members.  It
- * computes the average round-trip time and the average clock value, throwing
- * out samples outside the standard deviation.  The result is then used to
- * compute and send clock offsets to each member.

-/**
- * Protocol to discover subgroups; e.g., existing due to a network partition (that healed). Example: group
- * {p,q,r,s,t,u,v,w} is split into 3 subgroups {p,q}, {r,s,t,u} and {v,w}. This protocol will eventually send
- * a MERGE event with the coordinators of each subgroup up the stack: {p,r,v}. Note that - depending on the time
- * of subgroup discovery - there could also be 2 MERGE events, which first join 2 of the subgroups, and then the
- * resulting group to the last subgroup. The real work of merging the subgroups into one larger group is done
- * somewhere above this protocol (typically in the GMS protocol).<p>
- * This protocol works as follows:
- * <ul>
- * <li>If coordinator: periodically retrieve the initial membership (using the FIND_INITIAL_MBRS event provided e.g.
- *     by PING or TCPPING protocols. This list contains {coord,addr} pairs.
- * <li>If there is more than 1 coordinator:
- *     <ol>
- *     <li>Get all coordinators
- *     <li>Create a MERGE event with the list of coordinators as argument
- *     <li>Send the event up the stack
- *     </ol>
- * </ul>
- *
- * <p>
- *
- * Requires: FIND_INITIAL_MBRS event from below<br>
- * Provides: sends MERGE event with list of coordinators up the stack<br>

-/**
- * Protocol to discover subgroups; e.g., existing due to a network partition (that healed). Example: group
- * {p,q,r,s,t,u,v,w} is split into 3 subgroups {p,q}, {r,s,t,u} and {v,w}. This protocol will eventually send
- * a MERGE event with the coordinators of each subgroup up the stack: {p,r,v}. Note that - depending on the time
- * of subgroup discovery - there could also be 2 MERGE events, which first join 2 of the subgroups, and then the
- * resulting group to the last subgroup. The real work of merging the subgroups into one larger group is done
- * somewhere above this protocol (typically in the GMS protocol).<p>
- * This protocol works as follows:
- * <ul>
- * <li>If coordinator: periodically broadcast a "I'm the coordinator" message. If a coordinator receives such
- * a message, it immediately initiates a merge by sending up a MERGE event
- * <p>
- *
- * Provides: sends MERGE event with list of coordinators up the stack<br>
