Updated the Red Tide model

[arango]

The red tide model (RED_TIDE) was updated to include a Q10 mortality rate equation, as a function of temperature. It includes new input parameters in red_tide.in:

! Mortality rate Q10 equation parameters, as a function of temperature:
!
!   M_rate = Mor_a * Mor_Q10^[(temperature-MOR_To)/10] + Mor_b

         MOR_a == 0.04d0                         ! amplitude, 1/day

         MOR_b == 0.03d0                         ! intercept, 1/day

       MOR_Q10 == 10.0d0                         ! reaction rate base

        MOR_T0 == 15.0d0                         ! background temperature (C)

A couple of input parameters are also adjusted in red_tide.in for the Gulf of Maine:

! Maximum growth rate at optimal temperature and salinity [1/day]

          Gmax == 1.05d0                        ! Gmax

! Germination depth [cm]

            Dg == 0.18d0                         ! Dg

The BIO_TOY example gives the following Alexandrium Fundyense concentration:

Notice that I am plotting the LOG of the concentration.

Many thanks to Yizhen Li for the testing and update of the Red Tide Model.
