934	Added new module get_env.F	arango		"A new module **get_env.F** was added to retrieve system environmental variables, which can be decoded as logical, integer, or string values. For example, we can have in the environment:

 {{{
setenv ROMS_DEBUG 1
setenv ROMS_TRACE 4
setenv ROMS_HOME  /Users/arango/ocean/repository/git
}}}

Then, we can retrieve such values into a logical, integer, and strings variables, respectively, inside ROMS code by using:
 {{{
      Logical :: Ldebug
      integer :: Itrace
      character (len=256) :: roms_home

      status = get_env('ROMS_DEBUG', Ldebug)
      status = get_env('ROMS_TRACE', Itrace)
      status = get_env('ROMS_HOME',  roms_home)
}}}
Notice that **get_env** is a PUBLIC overloading function that decodes the string value of the environmental variables to another type of variable like integer and logical.

Currently, this capability is used in the ROMS-JEDi interface, but I can see its usage in the ROMS source code in the future."	upgrade	new	major	Release ROMS/TOMS 4.1	Nonlinear	4.0
