Common, stateful base class for both browser and NodeJS environments.
#Stateful Designed Classes
When designing certain kinds of classes it can be very useful to have a map or chart of all the potential States that might exist for the class. Not only all the states but also how they are allowed to transition between them. Quite often just the exercise of thinking up the States and their transitions will help you design the class more thoughtfully. Stateful gives you mechanic and then reinforces by preventing any invalid state changes. In addition, Stateful also allows you to have specific implementations by state (ie the doThat (™) method might behave different if your class is "loaded" and not "processing").
