What does it mean when a girl says "you're cool guy"?

Ok I brought this girl on a date tonight everything went well. Constant talking no dull moments, lots of laughing and smiling. After i dropped her off to meet her friends, I texed her letting her know we need to stay in touch because I’m going out of town for a week. She replies definitely you’re a cool guy :)
does that mean I’m still in? Or in the friends zone?
