/** This class provides a simple property source implementation mainly for
    testing purposes only.

    It maintains a hash table which maps property names to values (represented
    using WQLOperand objects).

    This class implements getValue() by simply looking up the property name
    in the map and fetching the corresponding value.

    The addValue() method is used to add property-name/value pairs to the 
    internal map.

    Since this class is intended for testing purposes, all of the methods
    are inline to avoid making the library any larger.
