A Position object points at a location between two characters.
 As the surrounding content is altered, the Position object
 adjusts its offset automatically to reflect the changes. If content is
 inserted or removed before the Position object's location, then the
 Position increments or decrements its offset, respectively,
 so as to point to the same location. If a portion of the document is removed
 that contains a Position's offset, then the Position's
 offset becomes that of the beginning of the removed region. For example, if
 a Position has an offset of 5 and the region 2-10 is removed, then
 the Position's offset becomes 2.
 
 Position with an offset of 0 is a special case. It never changes its
 offset while document content is altered.
