The menu is being composed from the header tags present in article (H1..H9) and links to the top
and the bottom of the page and scrolls the user to relevant section.

Extension is page-based so will work with any component (including K2).

Features:
- Configure which headers to include in the menu (for example, only H2 and H3 tags can be configured to be included);
- Flat or tree-like (for example, H2 and H3 could be merged into single menu level or be on different levels);
- Can have links to top and to bottom at the beginning of the menu and/or at the end.
- Smooth scrolling to anchors
- Configurable axis for scrolling

For best experience, AutoAnchor Menu can be used together with Absolute Floating Menu module or Fixed'n'Sticky, which will help AutoAnchor Menu stay onscreen.
