anchor: Body:getAngle
  Get the angle of the body.
  
  The angle is measured in radians. If you need to transform it to degrees, use math.deg.
  
  A value of 0 radians will mean 'looking to the right'. Although radians increase counter-clockwise, the y axis points down so it becomes ''clockwise'' from our point of view.
