   PetscViewerRegisterDynamic - Adds a viewer

   Synopsis:
   PetscErrorCode PetscViewerRegisterDynamic(const char *name_solver,const char *path,const char *name_create,PetscErrorCode (*routine_create)(PetscViewer))

   Not Collective

   Input Parameters:
+  name_solver - name of a new user-defined viewer
.  path - path (either absolute or relative) the library containing this viewer
.  name_create - name of routine to create method context
-  routine_create - routine to create method context

   Level: developer

   Notes:
   PetscViewerRegisterDynamic() may be called multiple times to add several user-defined viewers.

   If dynamic libraries are used, then the fourth input argument (routine_create)
   is ignored.

   Sample usage:
.vb
   PetscViewerRegisterDynamic("my_viewer_type",/home/username/my_lib/lib/libO/solaris/mylib.a,
               "MyViewerCreate",MyViewerCreate);
.ve

   Then, your solver can be chosen with the procedural interface via
$     PetscViewerSetType(viewer,"my_viewer_type")
   or at runtime via the option
$     -viewer_type my_viewer_type
