Subject: Implemented WarningCapacitor as a counterpart to ErrorCapacitor * 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
