process

public boolean process(java.util.Set<? extends javax.lang.model.element.TypeElement> annotations,
                       javax.annotation.processing.RoundEnvironment roundEnv)

1. For each class annotated with AutoService
   • Verify the AutoService interface value is correct
   • Categorize the class by its service interface
2. For each AutoService interface
   • Create a file named META-INF/services/<interface>
   • For each AutoService annotated class for this interface
     • Create an entry in the file
