Set size of cluster with configuration property, clusterSize.  Default is the number of CPUs.  Set clusterSize to 1 or lower to disable clustering.
Added autoReconnect feature to eCRUD to be used instead of MongoDB auto_reconnect feature.  The following config.db options can be used to set it up.

autoReconnect - boolean - controls whether eCRUD autoReconnect is enabled or disabled.  If diabled, eCRUD will exit when the connection to the database is lost.  Default is false.

reconnectRetryIntervalMS - number - Number of miliseconds to wait between attempts to reconnect to database. Default is 1000ms.
