+/**
+ * TPriorityMap class
+ *
+ * TPriorityMap implements a collection that takes key-value pairs with
+ * a priority to allow key-value pairs to be ordered. This ordering is
+ * important when flattening the map. When flattening the map, if some
+ * key-value pairs are required to be before or after others, use this
+ * class to keep order to your map.
+ *
+ * You can access, add or remove an item with a key by using
+ * {@link itemAt}, {@link add}, and {@link remove}. These functions
+ * can optionally take a priority parameter to allow access to specific
+ * priorities. TPriorityMap is functionally backward compatible
+ * with {@link TMap}.
+ *
+ * To get the number of the items in the map, use {@link getCount}.
+ * TPriorityMap can also be used like a regular array as follows,
+ * <code>
+ * $map[$key]=$value; // add a key-value pair
+ * unset($map[$key]); // remove the value with the specified key
+ * if(isset($map[$key])) // if the map contains the key
+ * foreach($map as $key=>$value) // traverse the items in the map
+ * $n=count($map); // returns the number of items in the map
+ * </code>
+ * Using standard array access method like these will always use
+ * the default priority.
+ *
+ * An item that doesn't specify a priority will receive the default
+ * priority. The default priority is set during the instantiation
+ * of a new TPriorityMap. If no custom default priority is specified,
+ * the standard default priority of 10 is used.
+ *
+ * Priorities with significant digits below precision will be rounded.
+ *
+ * A priority may also be a numeric with decimals. This is set
+ * during the instantiation of a new TPriorityMap.
+ * The default is 8 decimal places for a priority. If a negative number
+ * is used, rounding occurs into the integer space rather than in
+ * the decimal space. See {@link round}.
