/* This is a wrapper around "VolumeWeightedDataNodes.h".  That defined a class
 * which was very flexible.  In particular, you could use the same general
 * logic on different scales.  You could have one data node which watches
 * DELL with 10,000 shares in each bar, and another data node which watches
 * DELL with 20,000 shares in each bar.  In practice that's never done. 
 * Outside of some development tools, each stock has only one of these.  It
 * will use the number of shares per bar recommended by the overnight process.
 * This class will create find the appropriate VolumeWeightedDataNode object
 * using only the stock symbol as an input.
