## 🔧 Configuration

### Logging Configuration
CoreLib supports multiple logging frameworks. Configure your preferred logger:

```java
// Use with SLF4J (add slf4j-api dependency)
Logger logger = Logger.getLogger(MyClass.class);

// Use with Commons Logging (add commons-logging dependency)  
Logger logger = Logger.getLogger(MyClass.class);

// Use with Java Util Logging (built-in)

import java.util.List;
import java.util.Properties;
import java.util.regex.Pattern;

        });
        initialized = true;
    }

    /**
     * Returns the logger adapter factory.
     * <p>
     * If Commons Logging is available, returns a factory for using Commons Logging.
     * If not available, returns a factory for using java.util.logging logger.
