base/types/bindings/ruby. base/types_ruby is a historical artefact that
is going away.

Not really.

There are three ways to get these methods on the Ruby side.

 - write bindings manually using e.g. rice
 - extend the typelib types, e.g. reimplement the C++ methods on the
Ruby side. This is done as typelib plugins, which for the base types lie
in types/bindings/ruby/typelib/blablabla.rb and should be require'd by
types/bindings/ruby/typelib.rb. This method is a bit documented there:
http://rock-robotics.org/master/documentation/runtime/ruby_and_types.html.
The big issue with those is that they currently don't appear in the API
documentation (yuk)
 - write bindings automatically, but this is very experimental ATM

IMO, if the stuff you need on the ruby side is simple, use the typelib
extension method. If it gets to more complicated methods, wrap the type
manually. I hope that in fine the automatic can be hardened and
generalized to all Rock packages.
