extends java.util.TreeMap<ComparableMapKey4<K1,​K2,​K3,​K4>,​V>
    A 4-dimensional tree map. Instances of this class map tuples with 4 elements to value and provide some convenience functions to access elements without having to explicitly construct the tuples. The mapping is implemented by an ordered data structure that orders elements by pairwise comparison
