com.meapsoft.EDLChunk
Representation of an EDLFile Chunk Note that EDLChunk extends FeatChunk so that it can inherit the feature stuff from FeatChunk. This is really only to associate each EDL chunk with a set of features for visualization purposes (i.e. with ImagePanel, to see how the composers rearrange things) since the features associated with chunks in EDLs are basically irrelevant. @author Ron Weiss (ronw@ee.columbia.edu)

        Random rand = new Random();
        double currTime = 0;

                                   currTime);
        outFile.chunks.add(nc);
        currTime += nc.length;
        progress.setValue(progress.getValue()+1);
