-/** Class for preProcessing and postProcessing.
-
-    While cuts can be added at any time in the tree, some cuts are actually just
-    stronger versions of existing constraints.  In this case they can replace those
-    constraints rather than being added as new constraints.  This is awkward in the
-    tree but reasonable at the root node.
-
-    This is a general process class which uses other cut generators to strengthen
-    constraints, establish that constraints are redundant, fix variables and
-    find relationships such as x + y == 1.
-
-    Presolve will also be done.
-
-    If row names existed they may be replaced by R0000000 etc
