ENH: add blockMesh -write-vtk option

- generates a vtk file in an ASCII, XML format (blockTopology.vtu).

  More information than the equivalent obj file since it includes
  connectivity, cell shapes and cell IDs (equivalent to the block
  numbers).

Merge points instead of default topological merge
