SC4W - Rotate routine B

The purpose of an introduction to this rotation program the following example is a simple rotation of a group of coordinates about the vertical Z axis that will be rotated by 90 degrees the horizontal plane when viewed from above

The bearing of rotation is always "Clockwise" when viewing the plane from above towards the origin

Rotation routine "B"

a. Origin of rotation : a reference point 1 that will not change its values

b. Destination point : a reference point 2 current and future rotation position

c. Axis of rotation    : Easting , Northing or Vertical Axis - use surveyors left hand rule

d. Bearing                : it will change origin to destination bearing to the selected
