This service determines the loyalty level of a given portfolio owner, based on their total portfolio value. It also provides notifications whenever the loyalty level changes.

Currently the set of loyalty levels includes Basic, Bronze, Silver, Gold, and Platinum.

When it detects a change in level, it does a POST to an OpenWhisk action sequence, which builds a message and posts it to a Slack channel (#slack-test on ibm-cloud.slack.com).

This service expects query params named owner, total, and loyalty (the current loyalty level). It returns a JSON object containing the owner and their loyalty.

For example, if you did a GET to http://localhost:9080/loyalty-level?owner=John&total=123456.78&loyalty=Silver, it would return {"owner": "John", "loyalty": "Gold"}, and would post the following message to Slack: "John has changed status from Silver to Gold."
