+    When a variable is branched on it normally interacts with other variables by
+    means of equations.  There are cases where we want to step outside LP and do something
+    more directly e.g. fix bounds.  This class is for that.
+
+    A state of -9999 means at LB, +9999 means at UB,
+    others mean if fixed to that value.
