Detailed Description

A smart QObject implemenation of a TextRangeSet which listens to changes in the document. When a change happens it's changes the spatial of the ranges.

The stickymode is used to change the behavior of the changes the the textChange event. To put it simple, you should enable stickymode if this selection is the one you are using to modify the document

The delete mode is used to tell the rangeset if 'deleted' ranges need to be deleted or simply need to be moved
