trait RangeSampler extends Instrument[RangeSampler, ForDistributionInstrument]
Instrument that tracks the behavior of a variable that can increase and decrease over time. A range sampler keeps track of the observed minimum and maximum values for the tracked variable and is constantly recording and resetting those indicators to the current variable value to get the most descriptive possible approximation of the behavior presented by the variable.
When a snapshot is taken, this instrument generates a distribution of values observed which is guaranteed to have the minimum and maximum values of the observed variable as well as several samples across time since the last snapshot.
