*******************************************************************
* Function: int BehaviourFunction( const CKBehaviorContext& behaviorContext )
*
* Description : The execution function is the function that will be called 
*               during the process loop of the behavior engine, if the behavior 
*               is defined as using an execution function. This function is not 
*               called if the behavior is defined as a graph. This function is the 
*               heart of the behavior: it should compute the essence of the behavior, 
*               in an incremental way. The minimum amount of computing should be 
*               done at each call, to leave time for the other behaviors to run. 
*               The function receives the delay in milliseconds that has elapsed 
*               since the last behavioral process, and should rely on this value to 
*               manage the amount of effect it has on its computation, if the effect 
*               of this computation relies on time.
*
* Parameters :
*    behaviourContext    r   Behavior context reference, which gives access to 
*                            frequently used global objects ( context, level, manager, etc... )
*
* Returns : int, If it is done, it should return CKBR_OK. If it returns 
*                CKBR_ACTIVATENEXTFRAME, the behavior will again be called 
*                during the next process loop.
