 * not only execute code, but to get/set the contents of the message, before you choose to 
 * either block it or let it go on its way. The hooked function will be passed a msg_id, msg_dest, and entity index. 
 * The return value can be passed to unregister_message() to stop the message from being hooked */

/* The get/set _msg commands will fail if used outside a hooked message scope.
 * They should never be used unless inside a registered message function.
 * There are eight different ways of sending a message, five are ints, two are floats, and one is string.
 * These are denoted by iArgType.  argn is the number
 * of the argument. Exceeding the bounds of 1 to get_msg_args() is a bad idea. 
 * As of AMX Mod X 1.5, the middle parameter of set_* no longer does anything.
 * You cannot change the message argument type (as this would crash the mod anyway)
