MapEquality<K, V> class

Equality on maps.

Two maps are equal if they have the same number of entries, and if the entries of the two maps are pairwise equal on both key and value.

The equals and hash methods accepts null values, even if the isValidKey returns false for null. The hash of null is null.hashCode.
