 * @author Ariel Flesler
 * @version 1.2.5
 *
 * @id jQuery.fn.localScroll
 * @param {Object} settings Hash of settings, it is passed in to jQuery.ScrollTo, none is required.
 * @return {jQuery} Returns the same jQuery object, for chaining.
 *
 * @example $('ul.links').localScroll();
 *
 * @example $('ul.links').localScroll({ filter:'.animated', duration:400, axis:'x' });
 *
 * @example $.localScroll({ target:'#pane', axis:'xy', queue:true, event:'mouseover' });
 *
 * Notes:
 *	- The plugin requires jQuery.ScrollTo.
 *	- The hash of settings, is passed to jQuery.ScrollTo, so the settings are valid for that plugin as well.
 *	- jQuery.localScroll can be used if the desired links, are all over the document, it accepts the same settings.
 *  - If the setting 'lazy' is set to true, then the binding will still work for later added anchors.
 *  - The setting 'speed' is deprecated, use 'duration' instead.
 *	- If onBefore returns false, the event is ignored.
