    @brief
        Actionpoints are used by ActionpointController and all derived classes.
        Such classes will execute actions set in Actionpoints.

        In XML file one can pass an array of Actionpoints to a controller. Each
        Actionpoint can take action type, string and boolean or 
        action and two booleans as an argument.
        If action is set to fly, Actionpoint's position is assumed to be the desired
        location.
        Example XML code:

        @code
        <SpaceShip position="-2000, 1500, -1000" lookat="0,0,0" team=0 name="thisShipName">
          <templates>
            <Template link=spaceshipassff />
          </templates>
          <controller>
            <DivisionController team=0 formationMode="WALL">
              <actionpoints>
                <Actionpoint position="0,0,0" action="FLY" /> 
                <Actionpoint position="-1000,750,-500" action="ATTACK" attack="someShipName" />
                <Actionpoint position="-1000,750,-500" action="PROTECT" protectMe=true />
                <Actionpoint position="-1000,750,-500" action="PROTECT" protect="otherShipName" /> 
                <Actionpoint position="-1000,750,-500" action="FIGHTALL" />
               </actionpoints>
            </DivisionController>
          </controller>
        </SpaceShip>
        @endcode

        Example with loops:

        @code
        <SpaceShip position="-1500, 1500, -1000" lookat="0,0,0" team=0 name="thisShipName">
          <templates>
            <Template link=spaceshipassff />
          </templates>
          <controller>
            <DivisionController team=0 formationMode="finger4">
              <actionpoints>
                <Actionpoint position="  0,2000,-600" action="FLY" loopStart=true/>
                <Actionpoint position="  0,2000,-700" action="FLY"  />
                <Actionpoint position="100,2000,-700" action="FLY" />
                <Actionpoint position="100,2000,-600" action="FLY" loopEnd=true />
              </actionpoints>
            </DivisionController>
          </controller>
        </SpaceShip>
        @endcode
        
        One can also use other Worldentities instead of Actionpoints just like Waypoints, but those points
        will be included in loop.
        For more information read descriptions of the methods.
