Tracking data over time.
See also @ixfx/geometry for a Point/Points tracker.
Returns a new IntervalTracker instance. IntervalTracker
records the interval between each call to mark.
Keeps track of the total, min, max and avg in a stream of values. By default values are not stored.
Tracks the rate of events. It's also able to compute the min,max and average interval between events.
Returns a function to track changes in a boolean value
Returns a function to monitor value changes.
Frequency keeps track of how many times a particular value is seen, but unlike a Map it does not store the data. By default compares items by value (via JSON.stringify).

Base tracker class
A tracked value of type V.
Base tracker class
Tracks the rate of events. It's also able to compute the min,max and average interval between events.
Keeps track of keyed values of type V (eg Point). It stores occurences in type T, which
must extend from TrackerBase<V>, eg PointTracker.
