New mesh readers/writers, Grid and DistributedGrid refactoring

Jakub Klinkovskýrequested to merge
JK/mesh into develop

Changelog:

  • fixed various issues with mesh readers and writers
  • added tests for mesh readers and sample data
  • implemented VTIWriter and VTIReader, removed TNLReader
  • removed methods save and load from Grid, Mesh, MeshFunction, MeshFunctionView and VectorField
  • implemented MeshFunctionIO: reading and writing mesh functions using mesh readers and writers
  • tools, examples and benchmarks were updated to use functions from MeshFunctionIO
  • removed tnl-lattice-init - it was intended only for the tnl-lbm project which is deprecated (did not lead anywhere)
  • removed tnl-view - it has become obsolete, since all mesh functions are going to be saved directly in the VTK/VTU/VTI format and thus the conversion from .tnl files is not necessary
  • refucktored DistributedGrid
  • implemented PVTIWriter and PVTIReader, extended MeshFunctionIO for distributed grids
  • removed DistributedGridIO - it was replaced with PVTIWriter and PVTIReader
