Example/Usage:

StringIncubator gen = new StringIncubator(12); StringIncubator session = new StringIncubator();

StringIncubator gen = new StringIncubator(12, ThreadLocalRandom.current());

String symbol = StringIncubator.DIGITS + "ACEFGHJKLMNPQRUVWXYabcdefhijkprstuvwx"; StringIncubator tickets = new StringIncubator(23, new SecureRandom(), symbol);
