-The initiator topic, an SNS topic, is the common interface that all triggers will submit events to. The initiator topic is subscribed to by the initiator SQS queue (complete with dead-letter queue for resiliency) which in turn is subscribed to by the router Lambda function.

 #### How the router works
 In the context of trigger events where a new file is detected (payload_type=`url`), the router Lambda extracts the URL of the new file, instantiates a router object and attempts to match it up against of set of regular expressions defined in the router configuration file.
