Detailed Description

This class implements the vector for storing the line numbers at certain offsets/ The class allows the 'gap' position to contain a delta offset. Which means that.

all offsets after the gap are increased with the offsetDelta when searched. Inserting/deleting text this way usually only results in the changine of the offset delta. Which means speeeed

The line offset pointed at by each index is the first character in the given line.
