PERL PERL PROGRAM NAME: iTop_Mute_config.pm 
AUTHOR: Juan Lorenzo
DATE: July 27 2016 
DESCRIPTION Combines configuration variables
    both from a simple text file and from
    from additional packages.

USED FOR 
     Upper-level variable
     definitions in iTop_Mute3 
     Seismic data is assumed currently to be in
     su format.

BASED ON:
Version 1  Based on linux command "cat"
Version 2 based on Sucat.pm June 29 2016
   Added a simple configuration file readable 
   and writable using Config::Simple (CPAN)
    
  
Needs: Simple (ASCII) local configuration 
     file is iTop_Mute3.config

 Package control:
    filename is file, without a suffix!
    In some cases, numbers must be
    separated by commasi-- needed by 
    Seismic Unix

text file contains all the configuration variables in perl script

    base_file_name  		= 30Hz_All_geom_geom;
    gather_header  	= fldr;
    offset_type  		= tracl;
    first_gather   	= 1;
    gather_inc    		= 1;
    last_gather    	= 100;
    freq    		    = '0,3,100,200;
    gather_type    	= fldr;
    min_amplitude    	= .0;
    max_amplitude    	= .75;
