Fix invalid JSON in the Readme example
Objects no longer initialize themselves
Extract interpreter state into a World data structure
World is a structure
Organize thoughts and notes better
Rename RBinding#localVars -> lvars
Rename RObject#instanceVariables-> ivars
Rename RClass#instanceMethods-> imeths
RClass loses its behaviour
ruby.ds.objects.* become structures
RObject loses its behaviour
Convert all classes to structures

Conflicts:
	interpreter/src/ruby/ds/objects/RMethod.hx
Worldly (an obj w/ a world) and WorldWorker (helpful methods)

Idk if this is a good idea or a bad idea or what,
just kinda exploring the language, I guess.
Extract generic methods out of RubyInterpreter
Some playing with local vs inline functions

Looks like inline is better, but neither seem to be as good as I was expecting.
Small renamings/deletions/inlinings
Inline most of the WorldWorker functions
Experimenting with both local and inline, seems to work pretty well
RubyInterpreter#fill helper method is made local and inline
Add links to relevant docs on local/inline functions
