Hands-on: Xarray, NumPy, etc. for geographic data

[dhavide]

One or two notebooks illustrating a handful of NumPy & Xarray data structures & functions/methods that are used for the tutorial examples.

• Focus on examples that use geospatial data
• Try to minimise the total number of different functions/methods invoked (i.e., assume that novice learners will need to have the particulars of any function explained to them if they've never seen it before).
• Emphasise important features of the Xarray DataArray class vs. the NumPy array class

This can be about 10-20 minutes to deliver for a live audience (dependent on the learner's prior experience).
