Correlates the input signal against the provided vector of samples and outputs a phase and symbol timing estimate.

Tag Marking Delay (R): Tag marking delay in samples after the corr_start tag

Threshold (R): Threshold of correlator: 1-(Probability of False Alarm). Default 0.9.

 == Example Flowgraph ==
-Insert description of flowgraph here, then show a screenshot of the flowgraph and the output if there is an interesting GUI.  Currently we have no standard method of uploading the actual flowgraph to the wiki or git repo, unfortunately.  The plan is to have an example flowgraph showing how the block might be used, for every block, and the flowgraphs will live in the git repo.
