Class Description

 Implement the abstract 1-dimensional root finding interface using
 the Brent-Decker method. This implementation is based on the one
 in the GNU scientific library (v0.99).

RooBrentRootFinder(const RooAbsFunc& function) : RooAbsRootFinder(function)

Bool_t findRoot(Double_t &result, Double_t xlo, Double_t xhi, Double_t value) const
 Do the root finding using the Brent-Decker method. Returns a boolean status and
 loads 'result' with our best guess at the root if true.
 Prints a warning if the initial interval does not bracket a single
 root or if the root is not found after a fixed number of iterations.
