    @brief Used to load and store idXML files

    This class is used to load and store documents that implement
    the schema of idXML files.

        A documented schema for this format can be found at http://open-ms.sourceforge.net/schemas/.

        One file can contain several ProteinIdentification runs. Each run consists of peptide hits stored in
        PeptideIdentification and (optional) protein hits stored in Identification. Peptide and protein
        hits are connected via a string identifier. We use the search engine and the date as identifier.

    @note This format will eventually be replaced by the HUPO-PSI (mzIdentML and mzQuantML)) AnalysisXML formats!
