Note: lots of Mock-ist tests to be adjusted. That's pretty mechanical, but I'll wait to see whether anyone wants these changes first. |

I think the term 'data' is desperately confusing.
This is actually always a netcdf file variable, netCDF4.Variable (and not the variable's data).
Hence the rename !

I spent ages trying to fully understand this, and especially what was introduced in #213
(all that time ago!)
I think there is an excess of subtlety here, and I would have liked to remove some, but that is quite complicated !
So instead, here is an attempt to make the mechanisms clearer : Mainly, just renaming a few things, and adding a few choice comments which I wish I'd had to go on.
Frankly, I'd like to go further and ditch the "wrapper" implementation, which allows us to use a "cf_var" (of a CFVariable-derived type) as a proxy for the underlying netcdf variable object.
( "cf_var.cf_data" -- or as I'm now calling it, "cf_var.nc_variable" ).
Unfortunately there is a lot of other code using that, in both Pyke rules (example) and netcdf.py (example), so I think that change is just too big to include with this.
