* \brief ATSC SegSymSync
*
* Abstract class that establishes symbol timing and synchronizes
* with data segment boundaries.
*
* Takes a single stream of floats as the input and
* produces two streams as output. The first stream is the data samples
* and is of type float. The second stream is the tags, and is of type syminfo.
*
* The current GNU Radio interface doesn't currently support different
* types on the input ports (or output ports for that matter), but
* since they are the same size, it works.
