A generator is like a function, but after it "returns" it can be 
"called" again and it will resume where it left off. Local variables are 
preserved, and execution resumes after the statement that caused the return.
They're basically an automated method for creating an iterator object 
out of an opApply-like function.


In Python, you create them by using 'yield' instead of return.
