Nested For Loop
Moved main code inside another for loop, in order to print the logs for every bird within the "book". Modified the string function to only output either "better" or "worse" depending on how big the differnce in rating is. "rating" comment is appended outside this function now
Renames and Localized vars.
A few cosmetic changes. Localized some of the original variables to within their loops. Cleaned up some code.
