Replaced global variables by a new hydro_space struct that is part of space. This struct is then passed on to hydro_init_part, and used to initialize the Voronoi cells. For non SHADOWFAX_SPH schemes, this struct is empty. Replaced random_uniform declarations in some unit tests with the tools.h version. Added some more comments to 3D Voronoi code; it is now almost completely documented (meaning I almost completely understand it now).

Fixed wrong box size in 2D Sod shock that caused SHADOWFAX_SPH to crash. Added flag in const.h to enable or disable cell motion steering. Made sure cell centroids have all their coordinates initialized.

Cleaned up 1D Voronoi algorithm some more. Added SHADOWFAX_TOTAL_ENERGY flag and support for an isothermal EoS.

Constructing a 3D voronoi grid now seems to work. Still need to find a way to correctly initialize the box.

Wrote first working version of 1D moving mesh code. Got stuck in mesh steering and correct slope limiting.

Wrote 1D Voronoi cell generation algorithm and corresponding unit test. Algorithm is not coupled into swift yet.

Broke one of my own rules by doing too much in a single commit: implemented runner_extra_ghost, moved gradient calculations for both gradient types to new gradient loop, fixed bug in engine.c involving the number of links (which is larger with an extra loop), streamlined gradient methods, documented most GIZMO specific files. Second loop works.

Wrote dimension dependent matrix inversion method and corresponding unit test. Started making Gizmo dimension independent.

First seemingly working version of Gizmo hydro. Removed superfluous messages from vacuum Riemann solver.

Added GIZMO_SPH option in const.h. Made sure the resulting code compiles. It probably does not work correctly though.
