A python interface to UNIDATA's Udunits-2 package with CF extensions
copied from cf-staging / cfunitsA python interface to UNIDATAs Udunits-2 library with CF extensions.
Store, combine and compare physical units and convert numeric values to different units.
Units are as defined in UNIDATA
s Udunits-2 library http://www.unidata.ucar.edu/software/udunits/,
except for reference time units (such as 'days since 2000-12-1' in the 'proleptic_gregorian' calendar),
which are handled by the netCDF4 python package.
In addition, some units are either new to, modified from, or removed from the standard
Udunits-2 database in order to be more consistent with the CF conventions http://cfconventions.org/.
