 Find the master node process in a multi server cluster.
 
 This module finds the master node in a cluster by inserting the nodes in a mongodb and choosing the master by which node is the oldest. Each node checks into mongodb on a set timeout (default 1 minute). If the master node dies for whatever reason, mongodb will expire the record and the next node in line will become the master. Mongoose and a connection to a mongodb database is REQUIRED for is-master to work.
