        <p>This operation returns a <em>OverlapType</em> depending on how the interval
          in the target object and the timerange represented by the UTO object 
          overlap. If the OverlapType is 'OTNoOverlap' the out parameter represents 
          the gap between the two intervals. If OverlapType is one of the others, the
          out parameter represents the overlap interval.
          The definitions of the OverlapType's are:</p>
        <p></p>
        <list type="bulleted">
          <item>'OTContainer' - target objects lower and upper limits are,
           respectively, less or equal to and greater or equal to given object's.</item>

           respectively, greater or equal to and less or equal to given object's.</item>
          <item>'OTOverlap' - target objects interval overlap given object's.</item>
          <item>'OTNoOverlap' - target objects interval do not overlap given object's.</item>
