説明

　Creates and returns a UUID string. This method generates a 128bit UUID (universal unique identifier) generated from a random bit string.
　The UUID generation algorithm implemented in Kirikiri picks up environmental noise to some extent and generates a random bit string. However, we do not recommend using it for applications that require high security. However, it is considered "very non-overlapping" with other UUIDs.
