+/**
+ * The missing (SPL) Collection/Array/OrderedMap interface.
+ *
+ * A Collection resembles the nature of a regular PHP array. That is,
+ * it is essentially an <b>ordered map</b> that can also be used
+ * like a list.
+ *
+ * A Collection has an internal iterator just like a PHP array. In addition,
+ * a Collection can be iterated with external iterators, which is preferable.
+ * To use an external iterator simply use the foreach language construct to
+ * iterate over the collection (which calls {@link getIterator()} internally) or
+ * explicitly retrieve an iterator though {@link getIterator()} which can then be
+ * used to iterate over the collection.
+ * You can not rely on the internal iterator of the collection being at a certain
+ * position unless you explicitly positioned it before. Prefer iteration with
+ * external iterators.
