I believe all that info is in the ode document.  somewhere it explains how 
to use cfm and erp to mimick spring.

If I want a shock between two bodies, would it be more efficient to use 
calculate the simple spring physics and apply direct forces to the bodies, 
or create some kind of joint and use CFM and ERP to make it soft?

Also can someone clarify for me a bit more about ERP and CFM.  What values 
make them behave which way and what purpose do they serve for ode exactly?

Thanks,
  John Butterfield
