 * @brief  file reader for primal solutions
 * @author Tobias Achterberg
 * @author Marc Pfetsch
 *
 * This reader handles solutions in two formats:
 *
 * - <b>SCIP raw format</b>@n
 *   The format is as follows:@n@n
 *   line 1: "solution status: <status>"@n
 *   line 2: "objective value: <value>"@n
 *   line 3+i: \<variable name\> \<value\> (obj: \<objective coefficient of variable\>)
 *   @n@n
 *   Only nonzero values need to be listed.
 *   @par
 *   Example:
 *   @code
 *     solution status: optimal
 *     objective value: 1
 *     x1  1 (obj:1)
 *     x2  1 (obj:0)
 *   @endcode
 * - <b>XML format</b>@n
 *   This format is used by CPLEX, for example. For reading we require a section of @p
 *   \<variables\>. Each entry in this section consists of@n
 *   \<variable name="<name>" index="<number>" value="<value>"/>
 *   @par
 *   Example:
 *   @code
 *   <?xml version = "1.0" standalone="yes"?>
 *   <variables>
 *      <variable name="x1" index="1" value="1"/>
 *      <variable name="x2" index="2" value="1"/>
 *   </variables>
 *   </xml>
 *   @endcode
