/** Create before modifications of the document and destroy thereafter.
    Call SetDocumentModified() at an instance of this class instead of at
    ScDocShell.

    Remembers in the ctor ScDocument's AutoCalcShellDisabled and IdleDisabled,
    switches them off and restores them in the dtor, AutoCalcShellDisabled
    also before a ScDocShell::SetDocumentModified() call if necessary.
    In the dtor, if ScDocShell's bDocumentModifiedPending is set and
    bAutoCalcShellDisabled is not set, then ScDocShell::SetDocumentModified()
    is called.

    Several instances can be used in nested calls to ScDocFunc or ScDocShell
    methods to avoid multiple modified status changes, only the last instance
    destroyed calls ScDocShell::SetDocumentModified().
