Contains the currently-in-development project by HarvardX to bring the annotation tool currently living in the edX platform to a more accessible LTI implementation.
Updated Hxighlighter's h-range file to forego checking global position if the variable does not exist (as it does not for annotations created before switch to WebAnnotations).
Added check to see if in cases where the xpath matches, but the text does not, that nonalphanumeric differences (such as extra spaces or carriage returns) are accepted as still matching.
Added some padding to the lower end of the previous-next button
Added message when editing text target objects to warn authors of the implications to any annotations that may have been made beforehand. It also disables to text and requires manual override to edit.
Added fix to show the proper values for video links.
