Integration of custom VTK edition
This integrates a custom VTK/ParaView subset currently containing vtkXMLIO and all its dependencies as well as the foundation for in-situ visualization (ParaView's client/server implementation) as a CMake ExternalProject if it is not installed system-wide.
The compilation takes under 5 mins (on 2 cores) for the CLI config for me. Have a look at the developer guide on how to install ParaView once on your system. Alternatively you can have VTK 6.1 installed on your system.
A so called MappedMesh is implemented which gives VTK direct access to OGS mesh structures. See TestVtkMappedMeshSource.cpp for an usage example. For now, elements values are accessible as a cell data array with the name MaterialIDs.
New requirements
- VTK 6.1 or ParaView 4.2
- CMake 3.0.0 if you have none of the above and the custom ParaView edition gets build.
Things that are not nice
- On Windows parallel builds are not very efficient but you can make use of Ninja to speed things up (it is automatically used if the ninja executable is in the PATH), but Ninja builds only the Release config so you are not able to Debug ... so therefore this is disabled at the moment.
