Follow-Up Translations

This merge requests incorporates the following changes/additions:

• Allow the use of translator specific keywords in function calls, e.g. comment and cause for the DmpTranslator
• Generate valid Historys from given input flags. The user flags usually lack information (i.e. concrete parameter values, order of function calls, ...) to infer a real history. I loosed the definition of the word valid, to 'rerunning the history inferred from a DataFrame of user flags on the same input data, needs to yield the same user flags again'
• Make the different translators available through the CLI (i.e. the exe)
