Class derived from QgsMeshEditForceByLine that forces mesh based on polyline.
Forcing lines consist of line that the faces are forced to follow, that is edges of encountered faces have to be on theses lines.
Caller of this class has to add the lines from QgsGeometry instances with addLineFromGeometry() or addLinesFromGeometries() before applying the edition with QgsMeshEditor::advancedEdit()
