Typedefs
typedef void(*	AccelDataReadyCallback) (void *context)
	Called when a subscriber's sample buffer is full.
typedef struct AccelManagerState	AccelManagerState
	Opaque accelerometer subscription.

Functions
uint32_t	sys_accel_manager_get_max_samples_per_update (void)
	Get the maximum number of samples that can be batched per update.
void	accel_manager_init (void)
	Initialize the accelerometer manager.
void	accel_manager_enable (bool on)
	Enable or disable the accelerometer.
void	accel_manager_set_motion_backlight_enabled (bool enabled)
	Enable or disable the kernel's shake subscription for the motion backlight.
int	sys_accel_manager_peek (AccelData *accel_data)
	Read the current accelerometer sample.
AccelManagerState *	sys_accel_manager_data_subscribe (AccelSamplingRate rate, AccelDataReadyCallback data_cb, void *context, PebbleTask handler_task)
	Subscribe to accelerometer data.
bool	sys_accel_manager_data_unsubscribe (AccelManagerState *state)
	Remove a subscription and free it.
int	sys_accel_manager_set_sampling_rate (AccelManagerState *state, AccelSamplingRate rate)
	Change the sampling rate of a subscription.
uint32_t	accel_manager_set_jitterfree_sampling_rate (AccelManagerState *state, uint32_t min_rate_mHz)

	Set the buffer that receives a subscription's samples.
uint32_t	sys_accel_manager_get_num_samples (AccelManagerState *state, uint64_t *timestamp_ms)
	Get the number of samples currently in a subscription's buffer.
bool	sys_accel_manager_consume_samples (AccelManagerState *state, uint32_t samples)
	Release a subscription's buffered samples and refill its buffer.
void	accel_enable_high_sensitivity (bool high_sensitivity)
	Make shake detection sensitive enough to trigger on small movements.
