Make Backbone work with multiple models
Backbone contains dimension m, that should allow to iterate between models within Backbone. However, this has not been maintained and requires considerable work. On the other hand, Sceleton Titan can be used to run consecutive models. The downside is that it does not pass things in memory.
We should at least get a loop between UC and ED working. In addition to making the dimension m to work, we will need to allow passing values (initial or time series fixed, or prices) from higher level model to the lower level model.
