function str = twebstockrnd(spot, r, sigma, numsim, symbol)
%TWEBSTOCKRND stand-alone test driver for WEBSTOCKRND.
%   WEBSTOCKRND is the web demo stock price path simulation.
%
%   STR = WEBSTOCKRND(SPOT, R, SIGMA, SUMSIM, SYMBOL) creates 
%   stock price path graphic and HTML file.  Returns HTML output
%   in STR.
% 
%   Inputs 
%      SPOT   : Current Stock Price                     e.g. 60
%      R      : Annualized Expected Return (percent)    e.g. 10
%      SIGMA  : Annualized Volatility (percent)         e.g. 30
%      NUMSIM : Number of Simulated Paths               e.g. 4
%      SYMBOL : Ticker Symbol                           e.g. IBM
