Another thing i need to know about if this girl likes me?

i asked a question the other day to get feedback about if this girl in my cl likes me, basically to sum that one up , she would fiddle with her hair she remembers seeing me at my work a few days back while cles were out for weekend and asked me about it that day and today in cl she was really messing with her hair in my direction as i sit diagonal behind her and she kept exposing her neck where i could see, twirling her hair on the side closer to me and whenever i would look over between taking notes she would have her head sideways and appeared to be looking at me out of corner of her eye. any way, after cl was over i walked out behind her and said her name, when she turned around her face lit up and she was smiling, yes i know this could be a good sign, and i asked her to lunch, she had to work but got my number and txt me hers while we were walking and talking about our jobs and cl and, i find this odd but amusing at same time beer pong. Anyway when we got to her car , she asked what i drove i pointed it out and aid what it was as it was across a big lot and partially obscured by other cars, then she said well i gotta be at work in 20 mins. ill defiantly contact you so we can do something and we hugged. what i need to know is was this hug good bye significant and what significance does it have? also do you think she sees a relationship down the road? as soon as she first said she saw me at walmart the woman that sits next to me in cl said she likes you watch how she acts today thats how i noticed the signs as they were going unnoticed by me until then, i had thought she was cute since i saw her and watched her body language i decided i had to make a move im no good with this kind of stuff, i didnt get turned down for a number and she has contacted me since and i didnt get ignored when i talked to her are these good?
