<p>
IntervalCalculator is an interface class for a tools which produce RooStats ConfIntervals.
The interface currently assumes that any interval calculator can be configured by specifying:
<ul>
<li>a model,</li>
<li>a data set, </li>
<li>a set of parameters of interest,</li>
<li>a set of nuisance parameters (eg. parameters on which the model depends, but are not of interest), and </li>
<li>a confidence level or size of the test (eg. rate of Type I error).</li>
</ul>
The interface allows one to pass the model, data, and parameters via a workspace and then specify them with names.
The interface will be extended so that one does not need to use a workspace.
</p>
<p>
After configuring the calculator, one only needs to ask GetInterval, which will return a ConfInterval pointer.
</p>
<p>
The concrete implementations of this interface should deal with the details of how the nuisance parameters are
dealt with (eg. integration vs. profiling) and which test-statistic is used (perhaps this should be added to the interface).
</p>
<p>
The motivation for this interface is that we hope to be able to specify the problem in a common way for several concrete calculators.
