@gzclarence, which data would be useful to export?

I would like to plot the solution. Principally, I would like to export all the information in the solution. I can give examples like:

1. Series plot of production of a technology (flow) over the (base/atomic) time steps.
2. Geographical distribution of the accumulated production. (I can handle the geo map. But again, I need the series of production to get the sum).

I hope this helps. I will try to make my own export function. And in the next meeting we can discuss in person how it goes. :D

Plot functions were added in #191
The output to CSV is tackled in #295

Action: return DataFrames as an output 😄
