Constructor for bspline_4d

private elemental function bspline_4d_constructor_empty() result(me)

It returns an empty bspline_4d type. Note that INITIALIZE still needs to be called before it can be used. Not really that useful except perhaps in some OpenMP applications.

Type-Bound Procedures

procedure, public, non_overridable :: status_ok

returns true if the last iflag status code was =0.
