# Analysis tool for stock performance. Similar to the built-in advanced portfolio
# view, but does a better job at figuring out fees, taxes and dividens. Also
# computes lifetime wins/losses and yearly increas percentages to ease comparisons
# between stocks that you hold for different durations of time.
