// Census lets you define a Metric - something which can be measured, like the
// latency of an RPC, the number of CPU cycles spent on an operation, or
// anything else you care to measure. You can record individual instances of
// measurements (a double value) for every metric of interest. These
// individual measurements are aggregated together into an Aggregation. There
// are two Aggregation types available: Distribution (describes the
// distribution of all measurements, possibly with a histogram) and
// IntervalStats (the count and mean of measurements across specified time
// periods). An Aggregation is described by an AggregationDescriptor.
//
// You can define how your stats are broken down by Tag values and which
// Aggregations to use through a View. The corresponding combination of
// Metric/View/Aggregation which is available to census clients is called a
// ViewAggregation.
