A simple application to help keep track of the calorie intake of the users. The application provides the user with the ability to add food items that they have consumed, calculate their daily caloric needs based on their gender, height, weight, and activity level, and finally, to track the total calorie intake for the day. To run the project, first run "export API_KEY=". The APIKEY is the API key provided by USDA (https://fdc.nal.usda.gov/api-guide.html).
