CLASS ndi.gui.app.pipelineEditor

  NDI.GUI.APP.PIPELINEEDITOR - launch the graphical NDI pipeline editor

    OBJ = ndi.gui.app.pipelineEditor(SESSION)

    Opens the graphical NDI pipeline editor (ndi.cpipeline.edit) with the
    ndi.session SESSION pre-linked as the data source. The editor lets the
    user build and manage pipelines of ndi.calculator objects and run them
    against the linked session.

    This is a session GUI app (see ndi.gui.app.sessionApp): its constructor
    takes the ndi.session as its first argument, so it can be launched from
    the ndi.gui.navigator "Apps" menu.

    This class is only a thin wrapper. The editor itself, including the
    window it builds and the pipeline storage it manages, lives in
    ndi.cpipeline.edit; this app just forwards the session to it.
