bool Impala::Application::CheckParameteres	(	CmdOptions &	options,
		RawDataSet *	dataset,
		RawDataSet *	dataset2,
		std::vector< Feature::FeatureDefinition > &	featureDefs,
		std::vector< double > &	weights,
		String	resultname
	)

This function loops over the command line arguments to find (weight,featureDef)-pairs.

The vectors featureDefs and weights are filled with the findings
