Please use the following naming convention:

a) Each Unit in FLASH 3 is assigned an identifier (Grid, Driver, Hydro etc). 
   All of the public functions of a unit in FLASH 3 start with its unique 
   identifier, followed by an underscore, followed by the name of the function.
   For example "Driver_global", "Hydro_timestep" etc. In FLASH 2 even though 
   the modules do have identifiers (dBase, mesh etc), this naming convention 
   is used erratically.

b) The subunit names in FLASH 3 are composits of the unit name and
   some identifier that reflects the functionality of the subunit. For
   example all routines related to Lagrangian particles in the Grid
   unit are contained in the subunit GridParticles

b) All module scope variables available in a data module should begin with
   a unique two- or three- letter identifier, followed by an underscore, then
   followed by a description.  e.g. if Module is designated by "fm", then
   public variables should begin with "fm_":  
   real,save    :: fm_variableName

c) Non-data-module variables should NOT have an underscore in them.  
   Instead, they should follow a convention where they begin with a
   lowercase letter, and subsequent descriptive words are capitalized. e.g.
   integer :: numberDiscreteQuantities
   This convention will be enforced at the programming interface level, e.g. 
   in the argument calls to subroutines.

d) Where possible, use the prefix (fm_ in this case) for the non public 
   functions in a module/unit. Examples are functions fm_localFoo in 
   ModuleImpl1 and functions fm_localFoo1 and fm_localFoo2 in 
   ModuleImpl2 of this template. This naming convention is encouraged
   but not enforced.
