Sounds like a plan to me!

This is addressed by #21. CSVs are always read in as Hypergraphs. If the user prefers a symmetrical model then the Hypergraph can be converted into a factor graph.

Note, in the csv to hypergraph conversion zeros are teated as non-existent values. Is that the correct default behavior @marc-vuffray?

We need to implement the previous line of code in a clean way. That is, not inside of the optimization formulation.

Should variables be numbered from `0..variable_count-1` or `1..variable_count`?

it should be `1..variable_count`

I tried to get this working with various ipopt options, no luck. Can you provide an example of how to use this?

`1/sqrt(samples)` has been suggested.
