Rubinius::ToolSet provides a registry for code tools. These include
the Rubinius bytecode compiler and parser. These, in turn, depend on
other components like the AST and bytecode emitter and serializer.

ToolSets provide a mechanism for other languages to reuse as much of
the Rubinius code tools as are suitable for that language.
