* Revision 1.1.2.1  2007/11/28 18:50:47  caveenj
* Correction d'un bogue dans nc_rar pour le calcul des dimx et dimy
* On utilise maintenant la fonction ef_get_arg_extremes pour obtenir
* l'etendue complete du domaine.
* Ajout de code permettamt de traiter des variables 2D avec un indexwet2d
* et des variables 3D avec un indexwet3d.
*
* Ajout de la fonction rom_flip qui retourne un champ selon
* l'axe des Y (IROM) afin de faciliter l'affichage.

* In this subroutine we provide information about
* the function.  The user configurable information 
* consists of the following:
*
* descr              Text description of the function
*
* num_args           Required number of arguments
*
* axis_inheritance   Type of axis for the result
*                       ( CUSTOM, IMPLIED_BY_ARGS, NORMAL, ABSTRACT )
*                       CUSTOM          - user defined axis
*                       IMPLIED_BY_ARGS - same axis as the incoming argument
*                       NORMAL          - the result is normal to this axis
*                       ABSTRACT        - an axis which only has index values
*
* piecemeal_ok       For memory optimization:
*                       axes where calculation may be performed piecemeal
*                       ( YES, NO )
* 
*
* For each argument we provide the following information:
*
* name               Text name for an argument
*
* unit               Text units for an argument
*
* desc               Text description of an argument
*
* axis_influence     Are this argument's axes the same as the result grid?
*                       ( YES, NO )
*
* axis_extend       How much does Ferret need to extend arg limits relative to result 
*
