Not suited for adding multiple instances in document

[otacke]

Just adding this for documentation purposes.

The original TimelineJS (in combination with StoryJS) was not designed to handle multiple instances in a page's document (fixed id on an element that is then queried, guard against being loaded multiple times). That's not an issue if H5P.Timeline runs standalone. However, if multiple instances are supposed to be displayed (e.g. multiple H5P.Timelines in H5P.Column), only the 1st one will be rendered and be functional.
