Compilation warning on metis.h:337

Hi,

there is an extra coma on line 337 of metis.h file that causes a compilation warning (on some compilers):

METIS_DBG_MEMORY = 2048, /*!< Show info related to wspace allocation */

The fix is simple:

METIS_DBG_MEMORY = 2048 /*!< Show info related to wspace allocation */

Thanks,

Eric
