Title: Period slider

* Period slider (with `tangle.js`) at sandbox page
* Debug mode (to show FPS and shapes names) at sandbox page
* Fix discovered conflicts that happen when included library has its own `Element` class, which also may conflict with browsers `Element`. Solved temporary by renaming to `_Element`, may be it is better to introduce namespace.
* Fix access to tree as object instead of array.
