    This class presents the debug report to the user and allows him to veto report
    entirely or remove some parts of it. Although not mandatory, using this class
    is strongly recommended as data included in the debug report might contain
    sensitive private information and the user should be notified about it as well
    as having a possibility to examine the data which had been gathered to check
    whether this is effectively the case and discard the debug report if it is.

    wxDebugReportPreview is an abstract base class, currently the only concrete
    class deriving from it is
    wxDebugReportPreviewStd.

/**
    @class wxDebugReport
    @wxheader{debugrpt.h}

    wxDebugReport is used to generate a debug report, containing information about
    the program current state. It is usually used from
    wxApp::OnFatalException as shown in the
    sample().

    A wxDebugReport object contains one or more files. A few of them can be created
    by the
    class itself but more can be created from the outside and then added to the
    report. Also note that several virtual functions may be overridden to further
    customize the class behaviour.

    Once a report is fully assembled, it can simply be left in the temporary
    directory so that the user can email it to the developers (in which case you
    should still use wxDebugReportCompress to
    compress it in a single file) or uploaded to a Web server using
    wxDebugReportUpload (setting up the Web server
    to accept uploads is your responsibility, of course). Other handlers, for
    example for
    automatically emailing the report, can be defined as well but are not currently
    included in wxWidgets.
