Every release
 - Update README, vignettes
 - Update links
 - Any changes to CFtime? If so, release CFtime first

Every push to GitHub
 - Check the FIXMEs
 - Run document()
 - Run check()!

Next version
 - Fix auxll caching when same aoi is set
 - Labels, in .makeCoordinates
 - crossing the dateline: subset() and AOI -> https://github.com/r-spatial/stars/issues/700
 - CFAxisVertical calculate grids
 - Collect non-standrad evaluations in `nse` field in CFObject: report messages/warnings at the end of opening
      * dimension without NC variable, axis designation from name, CRS without grid_mapping when not lat-long
 - Testing
 - Set CRS, axis designations, etc in CFVariable and/or CFData, flag `isDirty` field in CFObject
 - CFData set units of data
 - Much more documentation, feature matrix, CF Conventions in R
 - GridMapping with methods to query CRS elements

Future
 - tapply straight from resource
 - Write NetCDF files
 - remove axes from bounds dimids
 - Analyze if sources belong together -> aggregation in CF terms
 - Select slice of data with `[`, tidyverse style
 - THREDDS catalog
 - DSG
 - MODIS binned L3

Notes:
 - CF objects should never read (or write) data themselves. The underlying NC
 objects could be in groups other than the CF object, such as ancillary CVs or
 formula terms. Pass the read/write request off to the respective NC object instead
