(protected) new RevisionsRequest()
The RevisionsRequest object is created when requesting revisions for a document comparison. It triggers events to indicate revision retrieval progress and has properties to get the retrieved revisions and status.
This constructor should not be used directly. Instead, a revisions request is created by PCCViewer.ViewerControl#requestRevisions.
Example
// A RevisionsRequest object is created by and returned from the call to the requestRevisions method
var revisionsRequest = viewerControl.requestRevisions();
