get_cep_slack_variables(test_result)

type OptResult has no field descriptor

This seems to be an error in get_cep_variables() in utils.jl, potentially here:

 if isempty(variables)
     throw(@error("$variable_type-Variable not provided in $(opt_result.descriptor)"))

Any thoughts on what happened? / was there a change in the most recent dev branch that we have to accomodate here?

There are two things:

• There are no Slack variables in the result, because neither lost_load_cost nor lost_emission_cost are included and no SLACK variables are setup
• The error message itself was trying to enter an outdated field. (I fixed that in a new commit)

Great, thank you!
