Reverse Engineering the Dartmouth Nutrition Menu Pt 2

From the first part, I had scraped an individual item's nutrition values and the daily meals. Now the priority is to be able to loop through all the elements in the daily meals and food it into some function that spits out the nutrition values. At the end of the loop, I should have all the nutrition information for the day.

Looking at the JSON, it seems each item is defined by a series of ids. The bigger picture is that with the food's id, I can extract its nutritional value with another request to the server. To get the id, I need to be able to parse the bigger JSON.

After examining the JSON, it seems that the items in the elements are referred by 2 id's: mm_id and mm_rank
