Do you really need a function *definition* in a header file?  Are you
trying to get something like a macro?  If not, you should just
put a *declaration* in the header file and include that in other files.
A declaration defines the interface, and the definition provides the
mechanism.  You don't want mechanism in header files in most cases.

In this normal case, there will be exactly one function or method definition
(e.g. in a .m or .c file), and but the corresponding header file may
be included many times in various places in the model.
