<h4>Test purpose</h4>
<ul>
<li>Create a set of draggable pin entitys, and a Polyline entity that uses the pins for positioning data, to create a line that can be shaped by the user</li>
<li>Create a color object which can be used to generate a range of colors between two defined colors</li>
<li>Create a template Wheel entity that we can use to colorise the line</li>
<li>Create an Animation object which will undertake a Display cycle to clear the canvas; then stamp the template entity along the length of the line, varying it's fillStyle color to reflect its progress along the line; then compose and display the final canvas output</li>
<li>Check that the color correctly alters along the length of the line, and updates as the user changes the shape of the line</li>
</ul>
