 Hello,

 I have provided an implementation for getting a "single-sided buffer" of a
 LineString geometry. It is based on the raw offset curves but nodes and
 cleans the edges. Please see an attached picture to see the existing
 RoundCap buffer, the new LeftSide buffer and the BothSides buffer.

 Applications for this single-sided buffering include getting clean offset
 curves of line geometries.

 Stephen W.
