Creates a spatial sub-path.
Parameters:
referencePath - the reference path that contains the sub-path
startLinkIndex - index of the start link
startPercentage - location of the start point represented as a percentage on the start link
endLinkIndex - index of the end link
endPercentage - location of the end point represented as a percentage on the end link
cost - sub-path cost
udio - user data IO implementation
Returns:
a spatial sub-path

                                                      SpatialNode[] nodes,
                                                      JGeometry geometry,
                                                      LODUserDataIO udio)
Creates a heavy-weight spatial path, which contains the object representation of the links and nodes on the path.
Parameters:
links - links on the path
nodes - nodes on the path
udio - user data IO implementation
Returns:
a heavy-weight spatial path
