Detailed Description

ROS laser scan controller.

• Starts a ROS node if none exists.
• Simulates a laser range sensor and publish sensor_msgs::LaserScan.msg over ROS.
• Example Usage:

      <model:physical name="ray_model">
        <body:empty name="ray_body_name">
          <sensor:ray name="ray_sensor">
            <origin>0.0 0.0 0.0</origin>
            <rayCount>683</rayCount>
            <rangeCount>683</rangeCount>
            <laserCount>1</laserCount>
            <displayRays>false</displayRays>
            <minAngle>-45</minAngle>
            <maxAngle> 45</maxAngle>
            <minRange>0.05</minRange>
            <maxRange>10.0</maxRange>
            <updateRate>10.0</updateRate>
