2014-06-06Implemented WarningCapacitor as a counterpart to ErrorCapacitorAdrian Kummerländer
* in difference to ErrorCapacitor this class doesn't throw an exception on "discharge" but returns the gathered warnings * adapted FunctionTransform and frontend error handling to include warnings * added static "try_create" method to TransformationFacade ** wraps construction error handling ** custom logic may be embedded using the std::function argument *** this was implemented to prevent unneccessary code duplication for handling both construction and generation errors * adapted FunctionTransform to return warning as "warning" nodes in the result tree ** added functional lambda expression factory method "handleErrors" *** returns a error handling lambda expression for a given ResultNodeFacade * implemented WarningGuard class in frontend executable ** guarantees warnings to be printed to std::cerr independent of any exceptions
