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.
This flowgraph and output show a QT GUI Label with an id:freq and a value of 0.1  Note that the output shows the <code>Label:</code> value 'Frequency' and the <code>Default Value:</code> value '100.0m'. The <code>freq</code> value is used to set the Signal Source Frequency.
