    \class HbDirectoryNameLocalizer
    \brief HbDirectoryNameLocalizer is used for localising directory names.
    
    Localisation is done if directory path matches one of the (pre)defined paths in hbdirectorylocalizer.xml
    If no localisation is available for directory empty string is returned.
    
    Example:

    \snippet{unittest_hbdirectorynamelocalizer/unittest_hbdirectorynamelocalizer.cpp,1}
