Produce containers topology from endpoints via processes...

[tomwilkie]

Mainly just refactoring:

• Allow the Renderers to recurse
• Add detailednode -> detailed node mappers

[tomwilkie]

This is the aim:

render.Reduce{
    render.LeafMap{Selector: report.SelectContainer, Mapper: report.MapContainerIdentity, Pseudo: report.InternetOnlyPseudoNode},
    render.Map{
        Mapper: report.MapProcess2Container,
        Renderer: render.Reduce{
            render.LeafMap{Selector: report.SelectProcess, Mapper: report.MapProcessIdentity, Pseudo: report.InternetOnlyPseudoNode},
            render.Map{
                Mapper: report.MapEndpoint2Process,
                Renderer: render.LeafMap{Selector: report.SelectEndpoint, Mapper: report.MapEndpointIdentity, Pseudo: report.InternetOnlyPseudoNode},
            }
        }
    }
}

As part of this change, I'll be moving all the rendering code from report to render/
