/** A wrapper for a UNO property set.

    This class provides functions to silently get and set properties (without
    exceptions, without the need to check validity of the UNO property set).

    An instance is constructed with the reference to a UNO property set or any
    other interface (the constructor will query for the
    com.sun.star.beans.XPropertySet interface then). The reference to the
    property set will be kept as long as the instance of this class is alive.

    The functions setProperties() tries to handle all passed values at once,
    using the com.sun.star.beans.XMultiPropertySet interface.  If the
    implementation does not support the XMultiPropertySet interface, all
    properties are handled separately in a loop.
