Cocos2d Android : 3장 . CCParticleSystem 사용법

//CCParticleSystem 사용법 입니다(expo.png 파일을 만들어서 asset에 넣어주심 됩니다)
//Cocos2d 라이브러리에 있는 CCParticleExplosion 클래스를 약간(?) 변경했습니다..
//터치 이벤트에서  schedule을 돌려야  CCParticleSystem  정상적으로 동작되는데 이유는 잘 모르겠네요..
//폭팔효과 외에도 CCParticleFireworks , CCParticleGalaxy ,CCParticleRain 등 다양한 효과가 있으니
   테스트 해보시길...^^;
