Copied label axes with ranges.
Enabled getStockChart when pressing 'enter' and replace old chart with new one.
ichart.yahoo.com seems to have re-arranged the order of its data.  Modified server to accommodate change.
Drawing initial column according to point-and-figure rules almost working.  Charts for "T" and "GOOG" work properly.  Both are one-range charts.  Chart for "V" is off by one.  It is a two-range chart.
Fixed axis mislabeling above breakpoint.  Chart plot still off by one.
Fixed chart off by one error when prices span two ranges.  e.g. "V."
Haven't tested comprehensively.
Corrected bottom tick for trendDown.  If downward trending stock only traverses one tick, though, program plots nothing.  e.g. "T" 37.33 -> 37.08.  Need to figure out how to handle that.
Discovered bug in axis labeling and corrected it.
("IBM" axis max of 252, but only had 10 $4 increments.)
Seems to be working.  Haven't thoroughly checked.
Fixed bottom breakpoint bug.  Seems to be working; not thoroughly tested.
