36  * \details
37  * This block creates tags to be sent downstream every 10,000
38  * items it sees. The tags contain the name and ID of the
39  * instantiated block, use "seq" as a key, and have a counter that
40  * increments by 1 for every tag produced that is used as the
41  * tag's value. The tags are propagated using the all-to-all
42  * policy.
43  *
44  * It also stores a copy of all tags it sees flow past it. These
45  * tags can be recalled externally with the data() member.
46  *
47  * This block is only meant for testing and showing how to use the tags.
