/** Hooks support. Hooks implement a chain-of-command pattern, and
 * are commonly used in most web servers as a mechanism of extensibility.
 *
 * The HandlerManager class will provide support for registering and maintaining
 * a list of modules implementing each hook.
 *
 * Each hook will have a name and an id. Name-based operations are slower, it is
 * recomended you use them only in non-critical code. The name-id association is
 * handled by NoteManager.
 *
 *
 *  @todo Merging. It is possible to have different hooks on different contexts
 *        ( server, context, servlet ), we need to merge them.
