/**
 * This library can be used to scan (part of) the class path for annotated classes, 
 * methods or instance variables.
 * 
 * Main advantages of this library compared with similar solutions are: 
 * 

 * light weight (**no dependencies**, simple API, 16 kb jar file) 
 * 
very fast (fastest annotation detection library as far as I know).
 * 
 * Maven configuration
 *  * <dependency>
 *    <groupId>eu.infomas</groupId>
 *    <artifactId>annotation-detector</artifactId>
 *    <version>3.0.2</version>
 * </dependency>
 * 
 * Example Usage
 * 
 * Put the {@code annotation-detector-3.0.2.jar} in the class path. No other dependencies are 
 * required! 
 * You can either scan the complete class path or only scan specified packages (see JavaDoc 
 * for more details).
 * 
 * // Scan all .class files on the class path
 * // Report all .class files, with org.junit.Test annotated methods
 * final MethodReporter reporter = new MethodReporter() {
 * 
 *   {@literal @}SuppressWarnings("unchecked")
 *   {@literal @}Override
 *   public Class[] annotations() {
 *     return new Class[]{Test.class};
 *   } 
 * 
 *   {@literal @}Override
 *   public void reportMethodAnnotation(Class annotation,
 *     String className, String methodName) {
 *     // do something
 * 
 *   }
 * };
 * final AnnotationDetector cf = new AnnotationDetector(reporter);
 * cf.detect();
 * 
 * References
 * Java Class file parsers
 * 
 * javassist
 * 
asm
 * 
Apache BCEL, considered outdated
 * 
jCFL, 
 * free but not open source
 * 
Java decompiler, also works on Linux, 
 * JAD does not!
