Description:
This routine provides a wrapper for the PDA_SURFIT spline interpolation routine.
The quirks of the algorithm are dealt with here so that SCULIB_SPLINE_REGRID does not have to
know anything about the interpolation routine.
Invocation
CALL SCULIB_SPLINE_PDA_SURFIT (NDP,
X_IN, Y_IN, DATA_IN, VARIANCE_IN, NX_OUT, NY_OUT, X_OUT, Y_OUT, DATA_OUT, STATUS)
