Generate Traces - function or class?

[beckydvn]

In the original Usage, the generated traces were handled in a Generate class. However, considering the idea that random trace generation is just one of many trace generation techniques, it probably makes more sense to use a series of functions instead. (Especially since Python doesn't support multiple constructors...) Thoughts?

Sounds good to me.

@alisonparedes : Can you think of any reason we'd like to keep things Class/object-centric for the generation?
