MVP v5: Text-Text Synopsis

[paulpestov]

For showcasing the Text-Text Synopsis it is necessary to implement a core behaviour of working with multiple texts in parallel.

AC:

• At least 2 Panels are loaded from whichever source
• There is an artificial Annotations Object located at Collection level that contains a list of arrays of CSS selectors to identify parallel elements in the texts
  • Each array can have an infinite number of items to enable a comparison of more than 2 texts
• There is a UI element between the panels where on click the user can enable the synoptical features
• On that interaction we setup the source/target scroll listeners
• The user can see the all parallel text passages at (almost) the same height each time he scrolls
