%description
Creates classes with reference semantics, similar to R's built-in
reference classes. Compared to reference classes, R6 classes are simpler
and lighter-weight, and they are not built on S4 classes so they do not
require the methods package. These classes allow public and private
members, and they support inheritance, even when the classes are defined
in different packages.
