add compile-time join path verification for 2-way assocs
Last modified: 2007-04-18 12:57:35 EDT
In plain English, when a two-way association is specified,
the join path for the first attribute is always the reverse
of the join path for the second attribute. The PDL compiler
should flag an error, if an association block violates
this invariant (due to a stupid programming error).
