ow available that allows to precalculate
these integrals and store their values for future use. This technique works transparently
for any p.d.f. stored in a <tt>RooWorkspace</tt>.

<p>One can store numeric integral values for problems with zero, one or two floating parameters.
In the first case, the value is simply stored. In cases with one or two floating parameters
a grid (histogram) of integral values is stored, which are interpolated to return integral
values for each value of the parameters.
