* \brief 1-to-1 stream annotator testing block. FOR TESTING PURPOSES ONLY.

* \details
* This block creates tags to be sent downstream every 10,000
* items it sees. The tags contain the name and ID of the
* instantiated block, use "seq" as a key, and have a counter that
* increments by 1 for every tag produced that is used as the
* tag's value. The tags are propagated using the 1-to-1 policy.
*
* It also stores a copy of all tags it sees flow past it. These
* tags can be recalled externally with the data() member.
*
* Warning: This block is only meant for testing and showing how to use the
* tags.
