get_namelists Subroutine

  subroutine get_namelists
!CMR, 17/11/2009: use gs2_diagnostics module to pick up public variables
!                 and routines to reduces maintenance of ingen.
!                 Should replicate this for other modules in future.
!CMR, 2/2/2011:   Have extended this to include use of theta_grid module:
!                 Strategy is simply to add two types of routines to modules:
!                      wnml_xxxxx   to write the modules namelists
!                      check_xxxxx  to perform the ingen checking inside the module
!                 More object oriented strategy, easier maintenance of ingen.f90 
!                 which is gradually shrinking.!
