- Use the correct value of 'h_max' in the construction of the caches in the vectorized DOPAIR1 routine. (fix #312)
 - Update the test27 unit test to also randomly perturb the smoothing length values.
 - Set a correct value for h_max in the test27 case and not just a loose upper-bound.
 - Call the non-vectorized version of DOPAIR1 for the corner interactions.

EAGLE_25 now produces the same number of time-steps whether running with or without vectorization. 

Documentation update. The MPI and vectorization macros will be expanded when generating the doxygen files.

Moved the testing into a function and tested each corner cell and each cell at the centre of each face.

Output the particle ID if a difference is found instead of the line in the file and print the particle property that differs.

Created a branching function for DOPAIR1, so that the scalar version is called if it is a corner interaction when the code is vectorised. Also fixed a bug with runner_dopair1_density_vec so that hi_max and hj_max are used to find how many particles to read into the cache.

Disabled GIZMO particle steering for vacuum particles

I disabled particle steering for particles with zero density, as they have weird sound speeds that mess up the steering algorithm. This fixes #271.

Update task dump processing

Fix some issues in autoranging, add new script to output simple stats
for pre-thread, step and rank. Add support for new drift_grav task.
Incorporate stats in higher-level processing scripts so that they
can be seen in the HTML pages.

Add a colour to keep similarity to previous scheme

Disabled GIZMO particle steering for vacuum particles. Disabled warning messages for unphysical values and pathological configurations.
