Fixed seg fault bug. Make sure that max_index_i[ci->count - 1] and max_index_j[0] are initialised to correct values when nothing is in range.

Updated testInteractions to use new vectorised interaction functions, both using one and two vectors.

Use intrinsics for vector operations as arithmetic overloading is not supported by the Intel compiler yet for AVX-512 vectors.

Revert "Add checks for particles that are at same position, this isn't allowed, and update the cell h_max to that of the particles after the initial ghost tasks have ran. This is needed before regridding if the h values of the particles in the IC are set to be smaller than reality (ends up looking like rebuilding failed as the particles are too far outside their cells)."

This reverts commit 3d12f382.

Add checks for particles that are at same position, this isn't allowed, and update the cell h_max to that of the particles after the initial ghost tasks have ran. This is needed before regridding if the h values of the particles in the IC are set to be smaller than reality (ends up looking like rebuilding failed as the particles are too far outside their cells).

Use the basename for the HDF5 files

These are relative to the container file and could include directory information (we assume XMF file is written into same directory as the snapshots).

Fixes #325.

See merge request !369

Use the basename for the HDF5 files as these are relative to the container file and could include directory information (we assume XMF file is written into same directory as the snapshots).

Subsize

Use separate parameters to determine when a pair or self interaction should be made a sub-cell task.

See merge request !365

Check if snapshot directory exists and add a digit to the output

Fix issue #321 

See merge request !368

This is a requirement of fopen()
