/** \brief Add animations to a model
*
* This method reads animation description tags from a model file
* and tries to add the corresponding animations to the 3D model.
*
* \todo Right now there's only one type of animation: movable control
* surfaces. Therefore this method receives a pointer to the control
* input class. If animations are added that need a different kind of
* input for their update() method, we need to decide how to pass all
* this stuff to initAnimations().
*
* \param model_file XML model description file
* \param model scenegraph of the 3D model
* \param fInputs pointer to the control input class
* \param anim_list list of all created CRRCAnimation objects
