/**
* Animation moves or rotates a group according to a given path.
*
* Animation is represented as list of "x, y, z" points.
* The x, y, z can be a translation or a rotation.
* Each time the engines render method is called the animation
* object will interpolate the group it is attached to, from one point
* to an other. When the animation has reached its end it will
* start over.
*
* Usage.
* Points are added to the animation with the 'add' method.
* The order of the points will be same in which they are added
* to the animation.
*
* Example:
* Group* group = new Group();
* StdAnimation anim = new StdAnimation(20, E_TRANSLATION);
*
* anim->add(0, 0, 0);
* anim->add(100, 0, 0);
* anim->add(0, 100, 0);
* anim->setEnd(0, 0, 0);
*
* group->addBehavior(anim);
*
* This example will create an animation which moves the group from origo to (100, 0 ,0)
* and then to (0, 100, 0) and back towards origo. Each movement will last for 20 engine
* ticks. When it reaches the end it will start over again.
* @see Group
