Issue 123: Re-jig result renders so that plots are stacked where appropriate
Project Member Reported by kris.west@gmail.com, Jun 17, 2010
Stephen requested that we alter the Chord and Structure plots so all systems appear on a single plot for each track. Segmentation plot supports this so just need to add another page to the report with the macro plots.

Also per metric bar charts comparing systems might be useful - again this is just an addition to the ResultRender implementations.
