## Functions provided for this class

AddGroup | Adds a group to the scope to which streams may be added |

AddStream | Adds a stream to the given group suitable for inputs and operations |

AddBuffer | Adds a fixed-view stream to the given group suitable for inputs and operations |

Rename | Renames the given scope group, stream or buffer |

AddPort | Adds an input to the stream from a port |

AddAnalog | Adds an input to the stream from an analog channel |

AddCustom | Adds an input to the stream from a custom injection |

AddOp | Adds an operation to act on the inputs of the stream |

ClearOps | Clears all inputs and operations from the given stream |

SetBuffer | Sets the contents of a snapshot stream |

SetCustom | Sets one of 32 custom analog values for the group |

GetSnapshot | Gets a block of the output stream with each input sample operated on, returns number of samples read |

GetOutputBlock | Gets a block of the output stream |

FindOutput | Searches back through the output history for a value, returns offset of found sample from TimeUS, 0 if not found |

FindBaud | Attempts to calculate the baud given a series of transitions for the stream, returns calculated baud |

AddOverlay | Adds a packet overlay to the stream at a given offset from the current time |

AddOverlays | Adds overlay packets to the stream by decoding the stream contents |

ClearOverlays | Clears existing overlay packets from the stream |

ClearAllOverlays | Clears all existing overlay packets from the stream |
