<p>Support for plotting vector fields.</p>

<p>Presently this contains Quiver and Barb. Quiver plots an arrow in the

direction of the vector, with the size of the arrow related to the

magnitude of the vector.</p>

<p>Barbs are like quiver in that they point along a vector, but

the magnitude of the vector is given schematically by the presence of barbs

or flags on the barb.</p>

<p>This will also become a home for things such as standard

deviation ellipses, which can and will be derived very easily from

the Quiver code.</p>
