* gravity: object {x:valueX,y:valueY} 
* container: define the limits where the object can be thrown 
                   "window" is the default
                   "parent" the object will be contained inside the parent
                   you can specify custom a container by giving array [x1,y1,x2,y2]
* shape: defines the shape of the object, by default is "box" and you can specify "circle"
* autostart: by default the effects start at mouse move 
* drag: boolean to specify if the object will be draggable or not, by default it is set to true
* impulse: you can specify an impluse to apply on the object by giving an object 
                   {
                        f: forceValue, // define the energy of the impluse (number)
                        p: pointDirection //define the direction on the impluse object like the gravity option
                   }
* bounce: defines the bounce effect of the body (value between 0 and 1) default 0, no bounce
* damping: defines the damping(*) effect value from 0 to infini, default 0 
* areaDetection: specify an array of areas, that when an objet enter those areas the event inarea is fired 
                 and outarea event fired when exiting
* collisionDectection : bool to activate or desactivate the collision detection 

* inarea : fired when an object enter and area specified in the option areaDetection
* outarea : fired when an object exit and area specified in the option areaDetection
* collision : fired when a collision happened between two objects 
* nocollision : fired when there is no collision
