(A) 2015-11-09  Add MAM_ExtData.rc + dito for GEOSachem

(A) 2015-11-09  Decorate MAM fields with prefix MAM or MAM7|MAM3 depending on the selected scheme

(A) 2015-10-30  Enable diagnostics from the CAM code + add these fields to the export spec

(A) 2015-10-30  Update the parameterization of in and below cloud wet scavenging 
                of aerosols from precip

(A) 2015-10-30  Two phase run method + revisit gas and aqueous chemistry sequence

(B) 2015-11-09  Revert to using CESM code for nucleation

(B) 2015-11-09  Revert to using CESM code for dry and wet sizes

(B) 2015-10-30  Number of vertical levels is hardcoded to 72 in modal_aero_amicphys.F90, 
                this needs to be changed to set the number of vertical levels at runtime.

(B) 2015-10-30  Refactor modal_aero_calcsize.F90
                + use 'fldcw => qc'
                + enable modal_aero_calcsize_diag() and call it before the AOT and other diagnostics

(B) 2015-10-30  Refactor modal_aero_wateruptake.F90
                + enable modal_aero_wateruptake_dr()
                + discard MAML_SizeMod.F90 and MAM_SizeMod.F90?

(B) 2015-10-30  Refactor modal_aero_initialize_data.F90 
                + enable 'call modal_aero_bcscavcoef_init'
                + is this the correct way: 'tot_spec = imozart+gas_pcnst-2'

(C) 2015-10-30  Include shr_kind_mod.F90
                + there two such files in GEOS-5, is it safe to add the CAM's version?

(D) 2015-10-30  Add new directory 'optics' or 'mie' and move the optics LUTs code in it.
                + validate the LUTs

(D) 2015-10-30  Check if the offline extinction calculator works

(E) 2015-10-30  Optics - treatment of non-spherical particles
