Implementation of SeeHistory feature

[Emmacho]

Ability to see on request, for any piece of wording, its ‘history’ (date of the change, which party asked for it; rationale for it; what alternatives were discussed

This feature would work as follows:

-Complements the above features and could simplify the interface. Rather than cluttering the text with lots of details by using HideShowDetails or ComparePrevious to show the details of all the wording, the user could just hover over any particular piece of wording to see the party and date when it was introduced (or deleted if it was only in an earlier version), any rationale or other notes visible to that user, and what the wording was before its prior change and after any subsequent change.
-An alternative implementation for a touch screen would be a menu item that would display the above history information of the selected text in a side panel.
-Selecting a version from the pop-up or side panel would allow the user to see the document version as it existed, in the same manner as the SeePrevious feature.
