This C++ library provides the following:

* A Collector interface for implementing classes that collect observed data and
  generate statistics for them
* A TopicStatisticsCollector interface for implementing classes that collect
  and perform measurements for ROS2 topic statistics. Classes for calculating
  ROS 2 message age and message period statistics are also implemented.
