v.surf.mass: Input should be vector "area" map?

[HuidaeCho]

@metzm The input option of v.surf.mass says Name of input vector point map, but I think it should be Name of input vector area map?

Given lines like G_fatal_error(_("No areas in input vector <%s>"), in_opt->answer); and for (i = 1; i <= nareas; i++) {...if (Vect_get_area_cats(&In, i, Cats) I think "area" is correct. I would almost say that the default description should be sufficient, but this has also an optional input and the type of features expected in the input is actually something we should make more prominent.
