Vincent Crabtree / Mbed 2 deprecated ColdStorageSystem

System to manage inventory for a cooler. Allows real time check in of products via RFID, as well as check out. Also includes a scale to weigh products upon check out, and has a real time temperature tracking system that sounds an alert if the cooler gets too hot.
