Upgrade examples to track Peter's automatically-generated C and Fortran bindings. These are still using a snapshot of the wrappers, slightly hand modified, but they are much closer to the final ones now. When the automated ones are ready and part of the build, these checked-in ones will no longer be necessary.

Added a dummy argument to constructors in Fortran examples because Mark Williamson's compiler didn't like them with no argument.
