-/*! \class doubleton_action
-    \brief Solve ax+by=c for y and substitute y out of the problem.
-
-  This moves the bounds information for y onto x, making y free and allowing
-  us to substitute it away.
-  \verbatim
-	   a x + b y = c
-	   l1 <= x <= u1
-	   l2 <= y <= u2	==>
-	  
-	   l2 <= (c - a x) / b <= u2
-	   b/-a > 0 ==> (b l2 - c) / -a <= x <= (b u2 - c) / -a
-	   b/-a < 0 ==> (b u2 - c) / -a <= x <= (b l2 - c) / -a
