See ticket #507
Initialize printlev_loc in module stomate_laieff: This module contains lots of subroutines and functions. To initialize printlev_loc I choose to create a global initialization subroutine for the module called from stomate_initialize. To be sure, non of the subroutines/functions were called before stomate_initialize, I added check with exit in each of the subroutines.
Added also global PRIVATE attribute.
