mjucker/aostools: aostools v2.3

Version used for M. Jucker (2020): Scaling of Eliassen-Palm Flux Vectors, Atmospheric Science Letters, DOI 10.1002/asl.1020.

Started transition to xarray data:

• ComputePsiXr(), ComputeVertEddyXr() (a9519d4)
• ComputeWstarXr() (28c46d2)
• ComputeRefractiveIndexXr() (3f22071)
• New function ComputeRossbyWaveSource() (3a53884)
• New function Nino(): Accepts SSTs and computes nino1+2, 3, 4, 3.4, ONI and TNI. (3a53884)

Minor additions and bugfixes.

• Changed function name ERA2Model() to StandardGrid() (cee2900)
• Add divergence calculation for ComputeWaveActivityFlux().
• Add possibility to use EOF as input to eof(): The function then projects data onto the input EOF and computes the corresponding PC (c192080)
• Add ComputeStreamfunction() (f0deda4)
• Bugfixes in ComputeWaveActivityFlux()
• Add Cart2Sphere() which takes arrow components and transforms them for plotting on a sphere. (607a048)
• constants.py now contains often used constants. Will be expanded in the future.
• Multi-axes projection figure with Projection() (58ee720)
• Converted spaces to tabs for python3 compatibility.
