Detailed Description

Representation of streamlines with motion of colors.

Class to visualize streamlines on a mesh, with a motion of color on the 
lines that simulates a animation of particles. Each line is drawn with 
only 2 colors : lineColor is the background color of the streamline, and
particleColor is the color of some parts of the line that move during
visualization. The field PoMesh::coloringType and PoMesh::valuesIndex
are not used by this class.
