    @brief An asteroid which can be destroyed. Some smaller asteroids are created and a pickup spawns. 

HANDBUCH:
o Die Collision Shape kann nur im Konstruktor hinzugefügt werden. Die XML-Argumente werden aber erst nach dem Konstruktor gesetzt. 
  Darum wird hier beim ersten Aufruf der tick()-Methode via putStuff() ein komplett neuer Asteroid generiert und der alte zerstört. 
o im Level-File includes/pickups.oxi importieren. 

OFFEN/Weiterentwicklung: 
o @TODO Add resource pickups. 
--> data_extern/images/effects: PNG's für die Pickups
--> https://www.orxonox.net/jenkins/view/Management/job/orxonox_doxygen_trunk/javadoc/group___pickup.html

o Density doesn't add up to 1...
o Does collision damage work properly
o Add sound effect (crunching etc. ) (No sound in space...)
o Explosion parts

ANDERORTS VERÄNDERTE SACHEN: 
Pickup-Zeug: 
o Pickup.h: createSpawner() neu public statt private
o PickupSpawner.h: Zugriffsrechte setPickupTemplateName() und setMaxSpawnedItems()
o PickupSpawner.h: In Tick() zwei Testbedingungen eingefügt.
o Pawn.h: Attribut acceptsPickups_ inklusive get/set. 

ERLEGTE FEHLER:
o Grössenabhängige Collision Shape -> putStuff-Methode, Werte noch nicht durchgesickert. 
o setHealth: maxHealth() des pawns setzen! 
o Asteroiden fressen Pickups: Argument in Pawn, Test darauf in Tick() von PickupSpawner. 
o i++ einfach ganz verhindern, ++i stattdessen. 
o Velocity didn-t get passed properly through the 2nd constructor. Used get/set instead. 
o Rand() geht bis zu riesigen Nummern! rnd() ist zwischen 0 und 1

NOTIZEN:
o SUPER
o Warnungsverhinderung anderswo: (void)pickedUp; // To avoid compiler warning.
o friend class Pickupable;
