[LORENE] New graphical functions

[Eric Gourgoulhon]

Dear All,

New graphical functions have been introduced in Lorene
to perform 2-D plots of a Scalar or a Vector without
having to use the old Cmp and Tenseur functions:

des_coupe_x(const Scalar&, ..) : draws isocontour lines
     of a Scalar in a plane X=constant.

des_coupe_vect_x(const Vector&, ...) : plots a vector field
    (with arrows) in a plane X=constant.

Besides, the functions performing 1-D plots of Scalar's,
namely

des_profile(const Scalar&, ...)
des_profile_mult(const Scalar**, ...)
des_meridian(const Scalar &, ...)

allow now to draw the boundaries between the domains
(new argument draw_bound at the end of the argument
list, set by default to "true").

Bon code !
