[Seth Y. <sya...@us...>]

Update of /cvsroot/opentreelib/otl/src/t
In directory sc8-pr-cvs3.sourceforge.net:/tmp/cvs-serv14043/src/t

Added Files:
	polylinespline3.t 
Log Message:
        - iceeey added incomplete unit test for otPolyLineSpline3.
          Only tests initial state, getLength(), and findNearest() so far.
