 few versions of this tool based on toy Monte Carlo, importance
sampling, Fourier transforms, etc.  The following concrete implementation
of the TestStatSampler interface are currently available</p>
<ul>
<li><tt>ToyMCSampler</tt>Uses a Toy Monte Carlo approach to build the
sampling distribution.  The pdf's generate method to generate is used to
generate toy data, and then the test statistic is evaluated at the
requested parameter point. </li>
<li><tt>DebuggingSampler</tt> Simply returns a uniform distribu
