[ODE] More info about timeStep and framerate

[Holger Urbanek]

Am I right that you are concerned about your calculations needing longer 
than the WorldSteps will occur?
This however is irrelevant for you, as long as you don't want to get 
real-time behaviour.

You just call the worldStep-function whenever you want the wold to move 
one, and it will move on the time as specified by stepsize. (normally in 
seconds). However be careful to choose small stepsizes to keep 
simulation errors small.

Espacially as yo are trying to do RF-Learning, real time is very 
uninterresting for you -- you will for shure interested in 
much-faster-than real time ;-), as learning takes for ages.

However I'm also at the very beginning of learning ODE.
