Construct an instance of the BuiltinMetric class. Values are case-insensitive unless otherwise noted.

"counter": the name of the metric, within the class. Must appear in the list of metric names for this class
found in the _builtIns dict. In this implementation, the builtin counter name is mapped to the OMI
