+/**
+ * EnumeratedArray is a fixed-size array container for use when an
+ * array is indexed by a specific enum class.
+ *
+ * This provides type safety by guarding at compile time against accidentally
+ * indexing such arrays with unrelated values. This also removes the need
+ * for manual casting when using a typed enum value to index arrays.
+ *
+ * Aside from the typing of indices, EnumeratedArray is similar to Array.
+ *
+ * Example:
+ *
+ *   enum class AnimalSpecies {
+ *     Cow,
+ *     Sheep,
+ *     Count
+ *   };
+ *
+ *   EnumeratedArray<AnimalSpecies, AnimalSpecies::Count, int> headCount;
+ *
+ *   headCount[AnimalSpecies::Cow] = 17;
+ *   headCount[AnimalSpecies::Sheep] = 30;
+ *
