Ah, this is a question I've had for a while. Last time I looked in to 
it, I didn't find a real answer, but my code started working, so I ran 
with it.

How do I define the difference between class variables and instance 
variables? Class methods and instance methods?

Currently, all my methods for my classes are defined as:

def method_name()
...
end

And my variables are all defined as:

@@var = ...

I couldn't figure out any other way to make variables available to 
methods of the class they belonged to, but doing it this way worked 
<shrug>.
