/**
 * TMap class
 *
 * TMap implements a collection that takes key-value pairs.
 *
 * You can access, add or remove an item with a key by using
 * {@link itemAt}, {@link add}, and {@link remove}.
 * To get the number of the items in the map, use {@link getCount}.
 * TMap 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>
