          **Key Arguments:**
              - ``coordinateList`` -- the original coordinateList.
  
          **Return:**
              - ``updatedCoordinateList`` -- the coordinate list with duplicated search areas removed
  
          **Usage:**

                  - add usage info
                  - create a sublime snippet for usage

              - update usage examples and text
              - update docstring text
              - check sublime snippet exists
              - clip any useful text to docs mindmap
