/** Bootstrapping native UNO.

    Bootstrapping requires the existence of many libraries which are contained
    in an office installation. To find and load these libraries the Windows
    registry keys HKEY_CURRENT_USER\Software\OpenOffice.org\UNO\InstallPath
    and HKEY_LOCAL_MACHINE\Software\OpenOffice.org\UNO\InstallPath are examined.
    These contain the paths to the program folder of the office which was
    installed most recently. Please note that the office's setup either
    writes the key in HKEY_CURRENT_USER or HKEY_LOCAL_MACHINE dependent on
    whether the user chooses a user installation or an installation for all
    users.
