Representing data in code

We are first going to expose the journeys that users can select from; so, create a new folder called meander in GOPATH and add the following journeys.go code:

package meander 
type j struct { 
  Name       string 
  PlaceTypes []string 
} 
var Journeys = []interface{}{ 
  j{Name: "Romantic", PlaceTypes: []string{"park", "bar",  
   "movie_theater", "restaurant", "florist", "taxi_stand"}}, 
  j{Name: "Shopping", PlaceTypes: []string{"department_store",  "cafe", 
   "clothing_store", "jewelry_store", "shoe_store"}}, 
  j{Name: "Night Out", PlaceTypes: []string{"bar", "casino", "food", 
   "bar", "night_club", "bar", "bar", "hospital"}}, 
  j{Name: "Culture", PlaceTypes: []string{"museum", "cafe", "cemetery", 
   "library", "art_gallery"}}, 
  j{Name: "Pamper", PlaceTypes: []string{"hair_care",  "beauty_salon", 
   "cafe", "spa"}}, 
} 

Here, we define an internal type called j inside the meander package, which we then use to describe the journeys by creating instances...
