/*------------------------------------------------------------------------------

    This routine does the following:

    	1.  Creates two entries in the association file for each relationship
	    formed by this new assocation instance. A binary association
	    (one with two references) ties two instances together. Suppose
	    there are two instances: I1 and I2. Then two entries are created:

		I2 -> I1
		I1 -> I2

	    For a ternary relationship, six entries will be created. Suppose
	    there are three instances: I1, I2, and I3:

		I1 -> I2
		I1 -> I3
		I2 -> I1
		I2 -> I3
		I3 -> I1
		I3 -> I2

	    So for an N-ary relationship, there will be 2*N entries created.

	2.  Verifies that the association instance refers to real objects.
	    (note that an association reference may refer to either an instance
	    or a class). Throws an exception if one of the references does not
	    refer to a valid object.
