Not enough ANALYTICAL checks in globaldefs.h

[kate]

There's a block of checks in globaldefs.h in which ANALYTICAL gets defined if any one of the ANA_* flags is defined. The tests in analytical.F are:

# if defined VISC_GRID || defined DIFF_GRID || defined SPONGE
#  include <ana_hmixcoef.h>
# endif

and

# if defined NUDGING_COFF
#  include <ana_nudgcoef.h>
# endif

These four flags should be added to the tests in globaldefs.h.

Yes. These flag were missing in the internal definition of ANALYTICAL.

I also added an example for the initialization of oxygen concentration in ana_biology.h when both BIO_FASHAM and OXYGEN flags are activated.
