Hdf5 simulation data export/import

[Robadob]

@ptheywood has been suggesting support HDF5 data import/export, especially for a standalone visualisation.

This is an experimental consideration at this stage, this issue will track notes/progress.

Licensing:

HDF5 uses 'szip', this is free for decoding, and non-commercial/education/research applications encoding, so I think we're ok.

Including source/binaries

They provide pre-built distributions. Less obvious from their website, they also have a bitbucket git repo, we could use this similar to google test (assuming it isn't difficult to build).

• Clone of the repo is ~138MB, so first cmake configure would be a bit slow
• Configure is very slow, does the thing where it checks for tens of headers, type availability and type size.
• Building initially failed for most items of 'ALL_BUILD', due to H5public.h(32): fatal error C1083: Cannot open include file: 'H5version.h': No such file or directory (This is supposed to be automatically generated)
  • There's a perl script to generate this, but I can't see any mention of this in the official CMake guide, which isn't very useful, the CTest is says to run errors (it appears to be trying to build a different version to what's checked out among other things).

Will attempt to use pre-built version instead

Static Linking

Static linking on Windows doesn't seem like a good idea, they don't support a static build that links against microsoft CRT.. So it won't link without changing from alot of FGPU2's default build settings.
