.. py:function:: fill_gaps_in_grid(array, key='nan', steps=['interpolate', 'extrapolate'], order=1, DEBUG=False)

   Interpolates nans by nearest neighbor method to fill gaps in arrays.
   Beware this method does not invoke bondaries correctly!
   This method does not work with array beeing a vector field! Hence, use componentwise
   and stitch together manually!

   :param - array: array with nans inside
   :param - key: indicates array entries that will be interpolated
   :param - method: as specified in scipy.interpolate.griddata,
                    i.e. use 'linear' for 3D data

   :returns: array without nans inside.

   .. rubric:: Example

   [[0,  1,  0],                 [[0, 1, 0,],
    [1, nan, 1],   -interpol->    [1, 2, 1],
    [0,  1,  0]]                  [0, 1, 0]]
