The `car' and `quote' functions work!
* scheme-interpreter/scheme-interpreter.fun
(SchemeInterpreterEnvironment): Update the scheme interpreter
environment in order to use the new definitions specified in SEXP
and SEXP_PARSER signatures.
(SchemeInterpreterEnvironment.sexp_to_action): the `car' and the
`quote' functions work!
(SchemeInterpreterEnvironment.application_type.apply): factor the
`Integer' and `Boolean' meaning into `Quotation' meaning in order
to be more uniform (Lisp should do a similar thing, is it true?)
