Review levelized cost
@OFR-IIASA thanks for this. I added the part related to relation_cost. As this cost can be related to relation_total_capacity, relation_new_capacity and relation_activity, I added all of them. I also improved the documentation and corrected some inconsistencies in indexes.
I just notice that your PR is opened under IIASA's remote. I assume you checked this before.
@behnam-zakeri would you please assign the PR to yourself or other people working so it doesn't come in the list for non-assigned PRs.
@behnam-zakeri it seems this PR was automatically closed as the branch to which this PR was originally made has been deleted. Can you reopen this PR and change the destination branch to main?
