Detailed Description

Input source for event consumers that will get events from the Storage Manager Event Server. This does uses a HTTP get using the CURL library. The Storage Manager Event Server responses with a binary octet-stream. The product registry is also obtained through a HTTP get.

There is currently no test of the product registry against the consumer client product registry within the code. It should already be done if this was inherenting from the standard framework input source. Currently we inherit from InputSource.
