#define VTK_FORTRAN_NAME	(		name,
			NAME
	)		name##__

The whole pupose 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_()

Passing array, Fortran start at 1 instead of 0.

1. Passing STRING array from fortran to C is a bit more tricky.
