/** A portfolio represents stocks that are owned.  The portfolio remembers
 * the name of each share (or group of shares) and its purchase price. 
 * The order in which the stocks are purchased is remembered so that a
 * "oldest sold first" calculation can be made for capital gain when a
 * stock is sold.  It is assumed that stocks are added to the portfolio
 * in the order they are purchased and this order never changes.  The stock
 * added in a single buy operation constitutes a "block".
 * The portfolio remembers these blocks and deletes them only when a full
 * block's worth of stock is sold.  A block is never split up or combined
 * with another block.  HOWEVER, if a stock sale only uses part of a block,
 * a new block is created to hold the remaining shares; such a block has
 * the same date and price per share as the original.  The fact that it has
 * the same date implies it has the same order as the original block -- it 
 * does NOT go to the rear of the queue.
