+   * This class inherits from CoinWarmStartPrimalDual, because that's what
+   * this warmstart really is. <br>
+   * For practical reason (integration in Cbc) this class also inherits from
+   * CoinWarmStartBasis. <br>
+   * This class stores a starting point (primal and dual values) for Ipopt.
+   * <br>
+   * <p>
+   * The primal part of the base class contains the value of each primal
+   * variable.
+   * <p>
+   * The dual part of the base class consists of three sections (the number of
+   * values is 2*numcols+numrows):
+     <UL>
+     <li> First, values for dual variables associated with the lower bound
+          constraints on structurals, i.e., primal variables (constraints
+	  \f$ l \leq x \f$); 
+     <li> Then values for dual variables associated with upper bound
+           constraints on structurals (constraints \f$ x \leq u\f$).
+     <li> the values for dual variables associated with regular constraints
+          (constraints \f$ g(x) \leq 0 \f$) 
+     </UL>
