[LORENE] #include-problem unites.h

[Eric Gourgoulhon]

Dear Reinhard,

Actualy the file "unites.h" is not similar to the other
headers files located in Lorene/C++/Include: it does
not contain any declaration which should have a global
scope. On the contrary unites.h is to be included in
the main body of a code, i.e. in a .C file, one should
always have

function(...){

 #include "unites.h"
 ....
}

and not  

#include "unites.h"
function(...){

....
}

Therefore, it will be an error to include unites.h
twice in the same function body.
This explains why there is not the traditional
writing

#ifndef __UNITES_H_
#define __UNITES_H_
...
#endif

in this file.

Best wishes,

Eric.
