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 FCPPLIBS variable in makefile to accommodate systems where the fortran compiler needs some extra libraries to link with C++. Also added a Makefile.mac with a possible good library combo.
