Reduce Parcel Lines

This option will remove redundant points from a parcel.
It walks along the parcel and considers three points at a time, says 1,2,3.
If the square offset of point 3 from the line 1-2 is less than the 'Max Offset' tolerance value
point 3 can be removed from the string.
It will then consider points 1,2,4 and repeat the process.

If the square offset distance is greater than 'Max Offset' value, it moves on to
the next set of points, 2,3,4.
This process is repeated all along the selected parcels.
The bearing and distance value of the affected lines are changed using the
point co-ordinates to compute a new bearing and distance value

If the Line type is specified, only lines with that line type will be processed.

In this example, points 2 and 3 would be removed and the parcel would become
points 1, 4,5, ...
