How to set up and validate locally

Update code lib/gitlab.rb so self.com? returns true.

Choose a few user_ids and create CreditCardValidation. Here I start with id 1 (root user)

user_id = 1
time = 1.year.from_now
expiration_date =  1.year.from_now.to_date

Users::CreditCardValidation.create(
  {"user_id"=>user_id, "credit_card_validated_at"=>time, "expiration_date"=>expiration_date, "last_digits"=>111, "holder_name"=>"foo bar", "network"=>"visa"}
)

Log in as admin, visit http://localhost:3000/admin/users/root/card_match
