Vibratingmotor

This document contains code for a vibrating motor service that initializes a vibrating motor and responds to button presses and proximity detections by turning the motor on or off. It includes header files for the service framework and vibrating motor code, defines constants for timer durations, prototypes private functions, and declares module level variables including a priority variable and deferral queue. The module code initializes the vibrating motor, posts events to the service framework, and contains the main service function that handles events and controls the motor by setting GPIO pins and timers.
