[pdp-discuss] Error-tweaking & scalarvallayerspecs

[Randall C. O'Reilly]

Frank -- a script with the network->Build(); and network->Connect(); function 
calls in it should work.  For the width, you might try adding a script that 
calls UpdateAfterEdit() on the layerspec after setting the new value.

btw, this kind of thing should be much easier to do in the new 4.0 version of 
the software -- we're working hard on getting a public beta version available 
soon..
