[rules-dev] idea for heat maps indicating usage

[Mark Proctor]

If someone wanted some fun with AOP here is a nice idea. Each node can 
track which rule and which part of the rule it was originaly from. Use 
AOP to log the number of propations in a node and then produce a heat 
map output, intially as a scale, you can click on a colour and it shows 
the rules in that range. Further to that the rules themsleves should 
have the patterns and even the indivual constraints annotated with a 
background constraint indicating their usage rate. If anyone gives this 
a go, please do use SWT so we can embed it in Eclipse, but a GWT 
equivalent would be good too :)

This could be extrapolated further with drill downs, recording the 
heatmap over time, and with a break down for which fact or field changes 
causes what usage rates.
