finished test code for old review upload and detail component
added google map api search, geolocation load functionaility to AddReview
integrated edit feature into AddReview, so renamed it as FormReview now.

Internally rewriting review components I made so it will use dispatch like other components, may not be report worthy tho

(2)
review components should apply the change in user login/signup
location based review list and some of friends feature

I am testing several word2vec model to find model that give better simiarity between flavors
I decide how we should implement recommendation algorithm(ex. updating Profile, Menu model)
