// Inspired by base2 and Prototype

// Modifications from original:
// - "Class" replaced by "adobe"
// - Refactored as a singleton class factory.  You call adobe.extend for all classes
// instead of calling the class's extend method as shown in the blog aritcle
// - createProxy added
// - newObject added
// - eventMap added
