Martini Routes for PUT and DELETE calls to users

update-delete.go

        //convert id from string to int64

        user.Id = f

        count, err := dbmap.Update(&user)
        checkErr(err, "Update failed")
        
        //checkErr above logs the DB issue but we also need to present the proper response to the client
        if count == 1 {
          newmap := map[string]interface{}{"responseText":"success"} 
          r.JSON(200, newmap)
