Implementation of seePrevious feature

[Emmacho]

Negotiator should be able to instantly go back to see previous versions of wording (either from earlier in current negotiations, or in previous contracts)”.

-After selecting an entire agreement, or just a set of clauses or subclauses, the user would see a button or menu item labelled “Show Previous versions”.

-Selecting this would show, alongside the current text, possibley a non-modal panel with a scrollable list with earlier dates, each with a few words highlighting what differed (e.g. number of words or clauses added, deleted, changed), and which party or author initiated the change) in that version.

-Selecting one or more of the dated versions, would show those versions alongside the current version (see also ComparePrevious, below).

• On any version displayed, there would also be a ‘Previous’ and ‘Next’ button pair, allowing the user to go back and forth one version at a time, with the date (and time if necessary) of each version always shown.

NB: There will limitations in the full implementation of this feature with contraction text not created in SoarNego. Possible challenges will be inaccessibility to the past metadata of the documents.
