[Rd] Class generator functions for reference classes

As of rev. 61035 in r-devel, setRefClass() now returns a generator 
function, as setClass() has done since 2.15.0.

The convenient style is now:
   mEdit <- setRefClass("mEdit",......)
   xx <- mEdit(data = xMat)

instead of
   xx <- mEdit$new(data = xMat)

The returned object still has fields and methods accessible as before.

See the "Value" and "Reference Class Generators" sections of 
?ReferenceClasses for details.

Thanks to Romain François for suggesting this.
