    # ==== About this implementation
    #
    # This implementation leverages the Braintree-authored ruby gem:
    # https://github.com/braintree/braintree_ruby
    #
    # ==== Debugging Information
    #
    # Setting an ActiveMerchant +wiredump_device+ will automatically
    # configure the Braintree logger (via the Braintree gem's
    # configuration) when the BraintreeBlueGateway is instantiated.
    # Additionally, the log level will be set to +DEBUG+. Therefore,
    # all you have to do is set the +wiredump_device+ and you'll get
    # your debug output from your HTTP interactions with the remote
    # gateway. (Don't enable this in production.) The ActiveMerchant
    # implementation doesn't mess with the Braintree::Configuration
    # globals at all, so there won't be any side effects outside
    # Active Merchant.
    #
    # If no +wiredump_device+ is set, the logger in
    # +Braintree::Configuration.logger+ will be cloned and the log
    # level set to +WARN+.
