Detailed Description

Wrapper around the information needed to generate the selection area There are two assumptions inside this class:

the start never changes, one instance of this class is used for one selection, therefore the start of the selection will not change, only end and direction of the selection will change. By direction we mean the direction in which the end moves in relation to the start, forward selection is when end is after the start, backward when its before.
The following changes might appear during selection: a. the end moves without changing the direction (it can move up and down but not past the start): only itE will be updated b. the end moves with changing the direction then itB becomes itE if the previous direction was forward or itE becomes itB
Internally it that is related to the start cursor is always at it[0] while it related to end is it[1], transition between meanings (itB/itE) is done with dir modifier;
