Collector

This class provides methods to collect metrics with no label, one label, or multiple labels, using overloaded definitions of the collect method.

Once the desired stats have been collected, the accumulated response string can be collected using the getCollection method.

Additionally, the reset method can be used to reset stat collection, when the desired stats have been collected from a Collector instance.
