Added database functionality for leaving meals
ordering meals by time, added button for leave meal that I attempted to hook up to the back end functions. leaveMeal function commented out in main-controller.js... other than that, minor cosmetic changes.
Update README.md

Added banner / temporary logo
quick fix to slogan (tell me what you think), and main.html 'link' section
Merge branch 'leaveMeal' of https://github.com/nfeliciano/mangiamo into leaveMeal
leave meal ALMOST works - still need to dynamically switch the button when you leave or join a meal.
Added database call for deleting meal from DB
Merge branch 'master' into leaveMeal

Merge pushes and minor changes
Fully functional leave meals front end and back end
Small changes to make the map working
I think this should fix the database multiple calls issue
Merge conflict fixed, along with removing  from mealTime
Merge pull request #114 from nfeliciano/leaveMeal

works as intended
