Derived variables

[vruijven]

It would be nice to have a handful of "standard" derived variables added to the database without the need to calculate them by hand. Initial candidates would be per capita values for final/primary energy (total), GDP, emissions, and intensities of energy/GDP, emissions/GDP, or emissions/energy. The Kaya decomposition indicators would be a good first step: https://en.wikipedia.org/wiki/Kaya_identity

Thanks @vruijven for this suggestion!

A first stab at this was done in the notebooks in the further_analysis folder of this repository.

I marked this suggestion as a good first issue and help wanted - it would be great if some motivated researcher would take a first stab at a script to generate more derived indicators and pull-request it to this repository, then we can include the variables in the next release.
