47    @brief SpaceBoundaries gives level creators the possibility to bar Pawns from leaving a defined area (until now this area is a ball).
48
49        Some attributes can/should be defined in the XML-File:
50        - 'position' : absolute position of the object of SpaceBoundaries in the level (usually 0,0,0)
51        - 'maxDistance' : defines the area, where a pawn is allowed to be (radius of a ball).
52        - 'warnDistance' : If the distance between the pawn of the human player and 'position' is bigger than 'warnDistance', a message is displayed to
53                            inform the player that he'll soon be leaving the allowed area. (not implemented yet!)
54        - 'showDistance' : If the distance between the pawn and the boundary of the allowed area is smaller than 'showDistance', the boundary is shown.
55        - 'reactionMode' : Integer-Value. Defines what effect appears if a space ship has crossed the boundaries.
56                                0: Reflect the space ship (default).
57                                1: Decrease Health of the space ship after having left the allowed area.
58                                2: Inverted Version of 0. Prohibit to fly INTO a defined area.
59        - 'healthDecrease' : a measure to define how fast the health of a pawn should decrease after leaving the allowed area (unnecessary if 'reactionMode' == 0).
60                                Recommended values: 0.1 (slow health decrease) to 5 (very fast health decrease)
61
62        Follow http://www.orxonox.net/wiki/SpaceBoundaries to get some further information.
63
64        Examples:
65        Two examples how one could include SpaceBoundaries in the XML-File. The first one uses reflection, the second one health decrease.

67        <SpaceBoundaries position="0,0,0" maxDistance="1000" warnDistance="800" showDistance="100" reactionMode="0" />
