Dino Dex First Refactor

Let me know when you have a few minutes.  I want to go over a few of the questions you had which I haven't yet done anything with.
You should initialize `@dinosaurs` in the constructor. This method should named something like `parse_csv`. No need for the local variable `dinosaurs`. Just work directly with the instance variable. On a side note, the local variable shouldn't have the same name as the instance variable. The latter is defined with `attr_accessor` so this can get confusing.
