Output breakdown of the objective value

[gnawin]

Description

Currently TEM only outputs the objective value of the problem, it is not straightforward to have a breakdown of the objective values.

For example, what are the investment costs, operational costs, and flow costs? As a quick fix, it is doable by going back to the definition of the objective function, the get the breakdown per component, as defined already, such as investment costs, operational costs, and flow costs. But it still requires developer level knowledge.

More detailed breakdowns are trickier, when you need a breakdown beyond what's an existing component of the objective function. For example, what is the production of a certain asset?

I propose to store the breakdown somewhere, so users can get it easier. Maybe a new structure?
Open to suggestions.

Motivation

This issue came out from the multi-year case study where we wanted to analyze the problem further by looking at different cost components, but this is applicable to all investment cases.
