-// Nomenclature note: capitalized names below (like Resource) are protos.
-//
-// Census lets you define a Resource - 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 Resource 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
-// Resource/View/Aggregation which is available to census clients is called a
-// Metric.
-
-
-// The following two types are copied from
-// google/protobuf/{duration,timestamp}.proto. Ideally, we would be able to
-// import them, but this causes compilation issues on C-based systems
-// (e.g. https://koti.kapsi.fi/jpa/nanopb/), which cannot process the C++
-// headers generated from the standard protobuf distribution. See the relevant
-// proto files for full documentation of these types.
