# A Hash-descended class for storing metric data in the NewRelic Agent.
#
# Keys are NewRelic::MetricSpec objects.
# Values are NewRelic::Agent::Stats objects.
#
# Missing keys will be automatically created as empty NewRelic::Agent::Stats
# instances, so use has_key? explicitly to check for key existence.
#
# This class makes no provisions for safe usage from multiple threads, such
# measures should be externally provided.
