/**
* A map that is sorted by value.
*
* This is an implementation of {@link Map} where entries are sorted by value, rather than by key.
* Such a tree may be useful as a priority queue where the cost of an entry may change over time.
* As such, the collections returned by {@link #entrySet()}, {@link #keySet()}, and
* {@link #values()} all implement {@link Deque}. The order of the entries will be updated on any
* call to {@link #put(Object, Object)}, or a call to {@link Collection#add(Object)} on the entry
* set. Additionally, if the values are mutable objects, whose costs may change, there is an
* {@link #update(Object)} method, which notifies the map that the given key may need to be
* repositioned. The associated collections also implement the {@link List} interface, providing
* fairly efficient implementations of {@link List#get(int)} and {@link List#indexOf(Object)}.
* Sequential access is best performed via {@link Collection#iterator()}, since this will use a
* linked list.
*
* A tree-based implementation of a value-sorted map
*
* The underlying implementation is currently an unbalanced binary tree whose nodes also comprise a
* doubly-linked list. Currently, it is not thread safe.
* TODO Consider changing to an AVL tree implementation
* TODO Consider implementing the {@link NavigableMap} interface
* TODO Consider making the implementation thread-safe
*
* Note this implementation isn't terribly smart, as it makes no efforts to balance the tree. It is
* also not thread safe.
*
* @param <K> the type of the keys
* @param <V> the type of the values
