* @brief REF file reader for structure information
* @ingroup FILEREADERS
* @author Gerald Gamrath
* @author Christian Puchert
* @author Martin Bergner
*
* This reader reads and writes a ref-file that defines the structur to be used for the decomposition.
* The structure is defined constraint-wise, i.e., the number of blocks and the constraints belonging to each
* block are defined. The constraints are numbered by the appearance in the problem.
*
* Constraints not mentioned in one of the blocks will remain in the master problem
*
* The format is the following
* - first line: \#nblocks \#ncons_block_1 ... \#n_cons_block_n
* - one line for each block with the indices of constraints to be put into that block separated by a comma
*
