[MITgcm-support] Regarding MITgcm biogeochemical packages

[Matthew Mazloff]

BLING is described in 
https://agupubs.onlinelibrary.wiley.com/doi/full/10.1002/2016JC012650 <https://agupubs.onlinelibrary.wiley.com/doi/full/10.1002/2016JC012650>
and it has evolved a bit since then with options to now include self shading, advection of biomass, and also includes silica
Its a bit more complex than DIC, but less complex than darwin. 
It is adjoint compatible.
