 * Default {@link HeadersMapFactory} which uses the {@link org.apache.camel.util.CaseInsensitiveMap CaseInsensitiveMap}.
 * This implementation uses a {@link org.apache.camel.util.CaseInsensitiveMap} storing the headers. This allows us to be
 * able to lookup headers using case insensitive keys, making it easier for end users as they do not have to be worried
 * about using exact keys. See more details at {@link org.apache.camel.util.CaseInsensitiveMap}.
