'''
This script generates a data file that can be read by gnuplot or similar
software. Columns, representing different data fields, may be generated via
command line arguments. Current available columns include:

- current cycle:       always present
- number of organisms: activate with '-o' flag

To run it, simply call it from within the ./bin/ directory inside the SALIS
main directory, such as:

../plugins/grapher.py -o def.sim.*.auto

Calling this will create a single DATA file including data from all files
matching the given pattern. This file may, in turn, be passed into gnuplot
for generating graphs.
