[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.

John
