- added correct support for hiding/showing all anotations based
on settings/flag
- added system for zooming in on a POINT on an object : closes #46
- experimented with solutions to make the annotations selectable:
ip
- fleshed out notes about interactions in readme
- added double tap info to infos-ui element
- started refactoring the whole viewer, as it is getting too messy:
 * extracted zooming, highligh and other "object effects" to
three-js-helpers repo
 * extracted obsolete code to attic/attic.js
 * started working on general utilities for re-use in utils.js
