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

Use intrinsics for vector operations as arithmetic overloading is not supported by the Intel compiler yet. Updated masking operations with new macros so that AVX-512 masking is supported.

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.

Correctly initialise the signal velocity of the SPH particles in the Minimal and Pressure-Entropy cases.

Implemented the changes in ls that prevent gizmo crashes in cases where the mesh is seriously distorted

Conflicts:

	tests/tolerance_125_perturbed.dat

Removed un-masked versions of the force interaction and incorporated them in runner_nonsym_force_2_vec with an if statement based on a hard coded mask_cond variable.

Initialize the signal velocity to be the particle's sound-speed. Prevents divisions by zero in cases where a particle has 0 neighbours.

Created a typedef for a mask object to abstract the mask creation away from the user and placed it in vector.h.

Updated plotting scripts for the hydrostatic halo case to be more SSH friendly and to read the correct parameters in the yaml file.
