+  and representing a `diff' between two CoinWarmStartPrimalDual objects. For
+  convenience, assignment, cloning, and deletion are visible to the world, and
+  default and copy constructors are made available to derived classes.
+  Knowledge of the rest of this structure, and of generating and applying
+  diffs, is restricted to the friend functions
+  CoinWarmStartPrimalDual::generateDiff() and
+  CoinWarmStartPrimalDual::applyDiff().
+
+  The actual data structure is a pair of vectors, #diffNdxs_ and #diffVals_.
