39		* SparseDoubleArray map integers to doubles. Unlike a normal array of integers,
40		* there can be gaps in the indices. It is intended to be more memory efficient
41		* than using a HashMap to map Integer to Double, both because it avoids
42		* auto-boxing keys and values and its data structure doesn't rely on an extra
43		* entry object for each mapping.
44		*
45		* <p>
46		* Note that this container keeps its mappings in an array data structure, using
47		* a binary search to find keys. The implementation is not intended to be
48		* appropriate for data structures that may contain large numbers of items. It
49		* is generally slower than a traditional HashMap, since lookups require a
50		* binary search and adds and removes require inserting and deleting entries in
51		* the array. For containers holding up to hundreds of items, the performance
52		* difference is not significant, less than 50%.
53		* </p>
54		*
55		* <p>
56		* It is possible to iterate over the items in this container using
57		* {@link #keyAt(int)} and {@link #valueAt(int)}. Iterating over the keys using
58		* <code>keyAt(int)</code> with ascending values of the index will return the
59		* keys in ascending order, or the values corresponding to the keys in ascending
60		* order in the case of <code>valueAt(int)<code>.
