snmpGetWily an snmp collector for EPA

I wrote snmpGetWily to allow some simple snmp metric collection by the epa.

Pseudo-pbd files describe the mapping of snmp OID's to Introscope metrics.
The values of OID's can be used in the metric name by to allow for more human readability.

Each device communication occurs on it's own thread so waiting and timeouts don't cause requests to back up.
