v0.4.1

Added

• Add scatter plots, i.e. particle plots with variable color and size markers.
• Add extra_quantities method to easily calculate extra quantities on the snapshot.
• Allow for setting array units, whether the array is rotatable, and whether it is a dust on derived arrays.
• Profiles are automatically generated from any 1d Snap quantity.
• Access individual dust quantities on profiles via '_001', etc.
• Read Phantom equation of state information to get pressure, sound speed, temperature.
• Add extra Snap quantities, e.g. Stokes number.
• Add extra profiles, e.g. Toomre Q.
• Allow accessing components of Snap quantities via '_x', etc.
• Calculate standard deviation on profiles.

Changed

• Use verbose names for all snapshot quantities, e.g. 'dust_fraction' not 'dustfrac' and 'velocity_divergence' not 'divv'.

Removed

• Remove Evolution object in favour of pandas DataFrame.
