public class FeatureMap
extends TreeMap<Double,Double>

A TreeMap extension for feature data - an indexed vector of values for a single feature. Keys are Objects (intended to be times or utterance start times). Values are Objects (intended to be the corresponding values for this feature). As it's a TreeMap, keys will be returned in ascending order, which is what we want when writing out to file.
