Test cycle re-render behaviour

[Stephen Kelly]

Hi,

In theory a compiled template should render to the same output each time it is rendered with the same Context.

When a template is rendered several times with a cycle tag, it does not render the same way each time. I think this might be an unsolvable issue because the CycleNode doesn't know when the template starts to be rendered the second time so that it can reset its cycle_iter variable.

If there are no better ideas on how to reset it, this should probably be documented.

All the best,

Steve
