/*******************************************************************************
* Function Name: GestureDetection
****************************************************************************//**
* @par Summary
* This function detects forward and backward gestures using
* two proximity sensors
*
* @return
* None
*
* @param[in]
* Proximity sensor information, gesture structure instance reference
*
* @param[out]
* None
*
* @pre
* None
*
* @post
* None
*
* @par Theory of Operation
* Logic to say left to right gesture is completed is given below
* 1) Both the proximity sensors are OFF
* 2) Left proximity sensor turned ON
* 3) Both Left and Right proximity sensors ON
* 4) Only right proximity sensor ON
* 5) Both the proximity sensors are OFF
* To determine invalid gestures following additional checks are implemented
* 1) Configurable debounce for each state
*
* @par Notes
* None
*
