[Rd] R6 "classname" and generator name

I'm writing some code that does a bit of introspection of R6 classes and am wondering about the "classname" parameter. Its the first parameter to the "R6Class" class generator generator function, and the few examples I've looked at on CRAN set it the same as the name of the generator function, for
