* @defgroup MOD_SIGNALSLOT Module for Signals and Slots
* @ingroup MOD_BASE
* @short Basic signal handling.
*
* This module introduces a simple signal-slot framework.
* Signals have a fixed list of arguments:
* <ul>
* <li>a void* pointer</li>
* <li>1st integer argument</li>
* <li>2nd integer argument</li>
* </ul>
* The actual type of the void pointer is defined by the signal and
* corresponding slot(s): Gwen checks the type at runtime and refuses to
* connect signals with slots which define this pointer to be of a different
* type.
* Any signal can be connected to any number of matching slots.
*
* The central object in this framework is @ref GWEN_SIGNALOBJECT. It holds
* a list of signals and slots for a given object.
*
