/**
 * \class QSeisPlotCurve
 *
 * This class is notified of changes by
 * its corresponding QSeisData object.
 *
 * It fetches automatically a free curve colour
 * for the plot is attached to (and "frees" the
 * colour on detach).
 *
 * When the curve is attached and only the column
 * number without data is available (due to preparse only),
 * the class emits the dataRequested() signal to fetch the
 * full data set. The "empty" curve is still directly
 * attached to the plot, but gets autotically updated
 * when the data has been completely processed.
 * (This way the user interface does not get blocked.)
