A read only class that describes a range of contiguous text. Such a range occurs when you select a section of text. The range consists of the anchor point of the selection, anchorPosition, and the point that is to be modified by actions, activePosition. As block selections are modified and extended anchorPosition remains fixed and activePosition is modified. The anchor position may be placed in the text before or after the active position.
