Attempt to interpolate wave/wind data with only two latitude values fails
The Interpolator2D appears to be unable to interpolate data, if the grid only has two latitude values. (Presumably, the same problem applies to the longitude axis.) The problem seems to be related to the RectSphereBivariateSpline class, which needs at least 3 grid points to work (?). Proposed solution: In the Interpolator2D constructor, check how many grid points are provided. If the number is less than 3, initialize a simpler interpolation object.
