interface for data transfer during grid adaption

Summary

The general interface for GridTransfer and DataTransfer classes

Details

  • A class GridTransfer is added that abstracts the grid coarsening/refinement and adds calls to data adaption
  • The DataTransfer class is used to define an interface for interpolation of data during coarsening/refinement of the grid

Discussion

  • Where to instantiate the GridTransfer class inside ProblemStat?
  • How to specify which DOFVectors are added to the DataTransfer?
  • All DOFVectors should be resized to the correct size and only some needs full interpolation. How to distinguish?
  • How to write and add custom interpolation functions?
  • Can we use the return values of preAdapt() and adapt() of the grid, to control when data interpolation is necessary?
  • @spraetor Then, maybe we should provide a way to turn adaptivity on and off and maybe set how often it is called. This should be an initfile parameter
  • Use Interface of dune/grid/common/adaptcallback.hh
