Check and correct the given scenarioSource:
Checks for errors a (possibly incomplete) scenario setup of irace and transforms it into a valid scenario.
checkScenario(scenario = defaultScenario())
The scenario received as a parameter, possibly corrected. Unset scenario settings are set to their default values.
This function checks that the directories and the file names provided and required by the irace exist. It also checks that the settings are of the proper type, e.g. that settings expected to be integers are really integers. Finally, it also checks that there is no inconsistency between settings. If an error is found that prevents irace from running properly, it will stop with an error.
