    This branch adds a utility function that can be used to visualize the
    structure of a 2D grid, including indices of cells, edges, vertices.
    
    It was written by Linus Seelinger (who is currently a HiWi in
    Heidelberg) and has already proven very useful while debugging some
    YaspGrid issues.
    
    It is entirely self-contained and should thus not have any impact on the
    remainder of dune-grid. Linus has also written a unit test.
    
    * linus/master:
      Add a grid visualization tool 'printgrid' that uses gnuplot to show the grid structure, indices etc.
    
    (cherry picked from commit 1190e518
