20190905 v1.0: changes to make in future release
- create custom msg with sensor_msgs::Range and covariance and output covariance with relationship as mentioned in datasheet on how accuracy changes with range and measuring mode.
- convert to nodelet verison [ committed on 20190919]
- add service call for zeroing range measurement
- modify the JHlidarLite lib for more functionality as mentioned in manual and garmin github page for arduino
- adding sort of median filter to account for sudden spikes in range measurment and smoothen out measurements.
- adding readme on how to use and ros wiki page
- (optional) add urdf with cad model
- add diagnostic publisher
- add filtered output
- add ablitiy to do insitu calibration or calculate co-eff for filter by running a diff node while static above 1m.
