-;;; series.el --- Hosting common series of numbers -*- lexical-binding: t -*-
-
-;; Author: William Carroll <wpcarro@gmail.com>
-;; Version: 0.0.1
-;; Package-Requires: ((emacs "24"))
-
-;;; Commentary:
-;; Encoding number series as I learn about them.
-;;
-;; These are the following series I'm interested in supporting:
-;; - Fibonacci
-;; - Catalan numbers
-;; - Figurate number series
-;;   - Triangular
-;;   - Square
-;;   - Pentagonal
-;;   - Hexagonal
-;;   - Lazy-caterer
-;; - Magic square
-;; - Look-and-say
