v3.0.0-beta.14

Added

• hoomd.hpmc.external.field.Harmonic - harmonic potential of
  particles to specific sites in the simulation box and orientations.
• Support cereal 1.3.1
• Guide on how to model molecular systems.
• version.floating_point_precision - Floating point width in bits
  for the particle properties and local calculations.
• hoomd.md.pair.LJ.tail_correction - Option to enable the isotropic
  integrated long range tail correction.
• hoomd.md.Integrator.linear_momentum - Compute the total system
  linear momentum. Loggable.
• hoomd.md.bond.Table - Tabulated bond potential.
• hoomd.md.angle.Table - Tabulated angle potential.
• hoomd.md.dihedral.Table - Tabulated dihedral potential.
• hoomd.md.improper.Harmonic - Compute the harmonic improper
  potential and forces.
• Tutorial on Organizing and executing simulations.
• C++ and build system overview in ARCHITECTURE.md.
• hoomd.hpmc.external.wall - Overlap checks between particles and
  wall surfaces.
• hoomd.md.pair.ansio.ALJ - an anisotropic Lennard-Jones-like pair
  potential for polyhedra and ellipsoids.
• New optional dependency: coxeter, needed for some ALJ methods.

Changed

• Support variant translational and rotational spring constants in
  hoomd.hpmc.external.field.Harmonic.
• [breaking] Renamed hoomd.md.angle.Cosinesq to
  hoomd.md.angle.CosineSquared.
• [breaking] hoomd.Box no longer has a matrix property use
  to_matrix and from_matrix.

Fixed

• Compilation errors on FreeBSD.
• TypeError when instantiating special pair forces.
• Inconsistent state when using the walls setter of a
  hoomd.md.external.wall.WallPotential.

Removed

• [breaking] Removed hoomd.md.pair.SLJ potential and wall. Use
  hoomd.md.pair.ExpandedLJ.
• [breaking] hoomd.Box.lattice_vectors property no longer exists.
