/**

* Description:

*

* An implementation of {@link apt.masterswitch.Masterswitch} using the SNMP

* interface to the APC Masterswitch.

*

* SNMP Transport is handled using the <a href="http://www.opennms.org">opennms joesnmp stack</a>

*

* Control of the device is achived by sending SNMP Messages as Datagram Packets to the

* Management Interface Board built into the Masterswitch Device

*

* Changes to status information on the masterswitch are detected by listening

* to events from a {@link apt.masterswitch.snmp.SnmpTrapDaemon}
