/*
 * Notre Dame Rocket Team Roll Control Payload Master Code V. 0.8.2
 * Aidan McDonald, 2/1/17
 * 
 * Most recent changes:
 * Moved GPS enabling to post-burnout
 * Reconfigured transmitter code to send different sensor data at different points in the flight
 * Configured packet transmission to create a standard data set and interpretive flags for the receiver code to use
 * Modified the gpsDataFlag to be a generic flag set if data is saved, until the GPS is enabled, in which case it reverts to its old role.
 * 
 * To-dones:
  * Basic switch-case structure
  * Incorporation of Adafruit sensor code
