- * Simple JavaScript Inheritance, by John Resig.
- * This provides a short syntax for organizing code into classes.
- * Taken from http://ejohn.org/blog/simple-javascript-inheritance/.
+ * A very simple method for defining a new class (constructor and methods) using a single hash.
+ * No support for inheritance is included because we really shouldn't need it.
