Livestock Production, concordance to CBS

[nk027]

There is an additional concordance table in the code, that maps "Meat indigenous, <...>" to CBS items. These are then added to the CBS. This is rather inconsistent, since some "Meat indigenous, <...>" remains unchanged and other observations are simply repeated, meaning we map e.g.: "Cattle" and "Meat indigenous, Cattle" to "Cattle" and "Meat, cattle" to "Meat, cattle".

[nk027]

So "Meat indigenous, <...>" is used to estimate mass of live animal trade. This seems a bit spurious and will be dropped for now.

Note that:

• "Cattle" refers to live animals
• "Meat, cattle" refers to beef
• "Meat indigenous, cattle" refers to beef from the country, used anywhere

Get tonnes and head counts.

[nk027]

So we need to adjust conc_live-cbs.csv for units if we want to add both(head and tonnes are availalbe). Since we did not do this before and e.g. bovine meat is in the CBS I'll only add headcounts.

Never mind, we also do this messy stuff in 1b (line 391), where we create the "Cattle" classifications, etc. This needs to be a separate issue, since actual concordance here (and earlier on with the fao-script) is not done properly - it's just used to drop some variables. See #49.
