Debug interactions

See merge request !443

Check that both input files have logged the same number of neighbours and make sure that the neighbour lists are long enough.

If the neighbour count goes above NUM_OF_NEIGHBOURS don't log the neighbour id but keep logging the neighbour count.

Find missing interactions in DOPAIR2 and vectorized version.

See merge request !465

Created a branching function doself1 and doself2 to switch between naive, serial and vectorised versions.

Don't remove rshift from hi_max and pass h_max to populate_max_index_no_cache_force. Fixes missing interactions in runner_dopair2_force_vec.

Add a print units

See merge request !463

Remove unnecessary dependency between sort and self/density tasks.

See merge request !461

Improvements to i/o and parallel-i/o

See merge request !460

Corrected typo in Minimal-SPH implementation that prevents neighbour number convergence in some cases.

Make sure the code compiles with vectorization switched on and using a different hydro scheme from Gadget-2.
