      Description

      Investigate the IRIS API for linear interpolation to see if we can interpolate many points at once. Alternatively can we cache the linear object so that the wrapping only happens once?

      The gridded -> ugridded linear takes 6hrs whereas nearest neighbour takes 175s.
      From profiling the problem is in two areas of the linear interface (see case study document):
      1) There is a copy of the data on call
      2) There is an append call on the data
