[CM] Grace help examples

[Heinrich Taube]

Yes, you are correct that some of the tutorials are stale -- they were  
originally designed for the Common Lisp environment and dont reflect  
the newer realtime/scheme environment. I think the solution will be to  
make the current tutorials reflect realtime/scheme (Grace), and only  
ship the older set with gracecl releases (assuming there is some  
solution to getting CLM  working in a non-snd scheme the GraceCL  
releases will be fewer and fewer)
best, rick
