<BR>
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Returns a weak interface object that represents this
 group.
 <p>
 A weak interface object has no life-cycle privileges over
 the group that it represents and therefore its users have
 no accountability. A weak interface object is safe to
 give away but holds no promise of sustained validity.
 <p>
 Whatever code gave away a weak interface object retains
 the power of terminating the group object from which it
 was obtained, thereby making the weak interface
 object invalid.
 <p>
 A weak interface object is immutable; its unref and stopApp
 methods do nothing. Its validity is exactly that of the
 group or interface object from which it was obtained.
 <p>
 A weak interface object can be obtained from an interface
 object, or from a real group object, or from a weak interface
 object. In the later case, the object returned may be
 the original weak interface object since such objects
 are immutable.
 <p.
 Whatever code obtains a weak interface object from a group object
 or regular interface object, remains entirely liable for invoking unref
 on the initial object before discarding it. Giving away a weak interface
 object is not equivalent to transfering ownerhsip of the original.</TD>
