uniform, non-rational B-Splines\\
Uniform means that the control points are evenly spaced\\
(in terms of the parameter t =(0..1).\\\\
This app shows how B-Spline segments come together to form \\
a longer spline curve. Several things are make geometrically clear \\
by actually plotting the curve. \\
First, colors are used so the individual curve segments standout. \\
Second, the repition of control points to force a spline curve to start \\
(or end) at a designated point. \\
Third, generally the curve does not evey pass through a specific control point.\\
