Tracking Metrics

Individual measured values are not sent to Application Insights. Instead, summaries of the values (mean, range, average, standard deviation) are sent. Note: Standard deviation doesn't quite work yet.

Before calculating summaries, non-finite values are removed (see is.finite). If there are no values in metrics, nothing is sent.
