/**
* The whole purpose of this header file is to allow us to 'wrap' a c library
* into Fortran. Here are the basic goals we should reach:
*
* 1. The symbol mangling in fortran is different than is C. For example if
* you do this fortran:
* CALL Foo()
* you either need to define a symbol:
* - void FOO()
* - void foo()
* - void FOO_()
* - void foo_()
*
* 2. Passing array, Fortran start at 1 instead of 0.
*
* 3. Passing STRING array from fortran to C is a bit more tricky
*
* For more information refer to:
* [ FORTRAN/C INTEROPERABILITY ]
* http://www.ibiblio.org/pub/languages/fortran/ch1-11.html
*
* [ Data Type Compatibility ]
* http://www.ictp.trieste.it/~manuals/programming/sun/fortran/prog_guide/11_cfort.doc.html
