Create example with loading agents from CSV in a demo + documentation about repast.simphony

[jozik]

For responding to the Repast interest mailing list:
Can read in a CSV like so (from here):

List<String[]> rows = new CSVReader(
				new InputStreamReader(new FileInputStream(fileName)))
				.readAll()

Replace the Humans agent creation in the Java Zombies model with this.

For the actual example we put in a new demo model, we'd want more attributes.

     String fileName = "data/initial_humans.csv";
		
		List<String[]> rows = null;

		try {
			Reader reader = new InputStreamReader(new FileInputStream(fileName));
			CSVReader csvReader = new CSVReader(reader, CSVParser.DEFAULT_SEPARATOR,
		               CSVParser.DEFAULT_QUOTE_CHARACTER, 1);
			rows = csvReader.readAll();
		} catch (IOException e) {
			e.printStackTrace();
		}
 
		for (String[] row : rows) {
			int id = Integer.parseInt(row[0]);
			int energy = Integer.parseInt(row[1]);			
			Human h = new Human(space, grid, energy);
			context.add(h);
		}
