27   	 * @brief  file reader for partial primal solutions
28   	 * @author Jakob Witzig
29   	 *
30   	 * This reader handles solutions in two formats:
31   	 *
32   	 * - <b>SCIP raw format</b>@n
33   	 *   The format is as follows:@n@n
34   	 *   line 1: "solution status: <status>"@n
35   	 *   line 2: "objective value: <value>"@n
36   	 *   line 3+i: \<variable name\> \<value\> (obj: \<objective coefficient of variable\>)
37   	 *   @n@n
38   	 *   Only known values need to be listed.
39   	 *   @par
40   	 *   Example:
41   	 *   @code
42   	 *     solution status: optimal
43   	 *     objective value: 1
44   	 *     x1  1 (obj:1)
45   	 *     x2  1 (obj:0)
46   	 *   @endcode
47   	 * - <b>XML format</b>@n
48   	 *   This format is used by CPLEX, for example. For reading we require a section of @p
49   	 *   \<variables\>. Each entry in this section consists of@n
50   	 *   \<variable name="<name>" index="<number>" value="<value>"/>
51   	 *   @par
52   	 *   Example:
53   	 *   @code
54   	 *   <?xml version = "1.0" standalone="yes"?>
55   	 *   <variables>
56   	 *      <variable name="x1" index="1" value="1"/>
57   	 *      <variable name="x2" index="2" value="1"/>
58   	 *   </variables>
59   	 *   </xml>
60   	 *   @endcode
