* @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
