        @brief Executes the FeatureFinder using the given algorithm

        There are several constraints for the @p input_map.  They are tested before
        the algorithm starts.  It must only contain MS 1 level scans and you
        have to call updateRanges() before passing it to this method.
The input map is sorted by RT & m/z if thats not the case.
Furthermore we throw an Exception if the data contains negative m/z values,
as this will disturb most algorithms.
