This function allows plotting of colored 3D arrows by generating patch
data (faces “F”, vertices “V” and color data “C”). The patch data which
allows plotting of 3D quiver arrows with specified (e.g. colormap driven)
color. To save memory n arrows are created using only n*6 faces and n*7
vertices. The vector "a" defines arrow length scaling where a(1) is the
smallest arrow length and a(2) the largest. The input c specified color data. Use the PATCH command to plot

Renewed as included in gibboncode.org
Fixed arrow length scaling bug for equal length vector input. Added color input option and added comments and expanded example for color specification.
