Notes on updating Timeline
---------------------------

1. Add the custom PrimeFaces CSS at the bottom of timeline.css

/**************************/
/** Custom PrimeFaces css */
/**************************/

2. Remove all sourceMaps from both CSS and JS files. You can use Regexp in NotePad++ to remove \/\*(.*?)\*\/

Example: /*# sourceMappingURL=vis-timeline-graph2d.min.css.map */

3. Remove this last line of 0-vis-timeline.js to remove the source mapping URL

//# sourceMappingURL=vis-timeline-graph2d.min.js.map
