#### What did we implement:
in the Opendax, there is no way to deposit or withdraw for fiat,
so we use the Vandar as a third party to connect real banks for deposit and withdraws.<br />
for talking with The Vandar, we implemented a new service named VandarService (vandar_service.rb).<br />
VandarService has four part, Login, Deposit, Withdraw, Transaction

##### login part:
this part is used for login in the Vandar with mobile and password that these two must exist in the config file<br />
this part has a `login` method that automatically calls when creating object from this service

##### deposit part:
this part is used for doing deposits<br />
this part has a three methods:<br />
    -`generate_token`: use for generate unique Bank Gateway token
    -`transaction`: use for finding specific deposit in the Vandar
    -`verify`:  use for verify specific deposit in the Vandar

##### withdraw part:
this part is used for doing withdraws<br />
this part has a four methods:<br />
-`list_withdraw`: use for listing withdraws (never use in process)
-`info_withdraw`: use for get specific withdraw information from the Vandar
-`delete_withdraw`:  use for delete specific withdraw in the Vandar (never use in process)

##### transaction part:
- `list_transactions`: use for listing transaction with fromDate and toDate as parameters (use it in withdraw Job)

#### note:
we use Faraday Gem to send request to vandar
