/**
 * @class LookAt
 * @extends jibo.bt.Behavior
 * @memberof jibo.bt.behaviors
 * @description Makes Jibo look at a 3D point in space.
 *              `LookAt` has two modes. In single-shot mode, this behavior makes Jibo look at the 3D point returned
 *              by `getTarget` and succeeds when Jibo reaches his this target. In continuous mode, `getTarget` is
 *              called every frame, and this behavior will remain in progress indefinitely until explicitly stopped by a
 *              parent bahevior or a decorator.
 * @param {Object} options See {@link jibo.bt.Behavior|Behavior} for all options.
 * @param {Function} options.getTarget Returns a {@link jibo.bt.behaviors.LookAt.Point3D} object.
 * @param {boolean} [options.isContinuous=false] `true` if this behavior is in continous-mode. `false` if in single-shot look-at.
 * @param {Function} options.config Called and passed a {@link LookatBuilder} object for configuration purposes. Do not call {@link LookatBuilder#startLookat}. This is called automatically by the behavior.
