v0.6.1

Added

• Snap.sinks attribute has more features.
• Cross section interpolation in a non-xy plane specified by a normal vector to the plane.
• Snap.rotate can be set by an axis vector and angle as opposed to a scipy Rotation object.
• discs module to analysis.
• filters module to analysis to set SubSnaps easily.
• 'id' array on Snap to help track particles.
• Function to plot the smoothing length as a circle.
• Profile method to generate a function from a profile to help create particle filters, for example.
• Simulation method to create a particle array over the whole simulation.

Changed

• Snap.available_arrays does not reference sink particles; see Snap.sinks.available_arrays.
• Profile.plot units are now consistent with visualize functions.
• Dust profiles in Profile are now distinguished by whether they are mixture (dust/gas) particles or dust-only particles.

Fixed

• Setting origin in extra quantities.
• All analysis functions have better physical units support.
• Bug in Snap.num_particles_of_type.
