class TMVA::RootFinder: public TObject

         User Class to find the Root of one dimensional functions.
         The GSL Methods are implemented in MathMore and they are loaded automatically
         via the plug-in manager

         The possible types of Root-finding algorithms are:
         <ul>
         <li>Root Bracketing Algorithms which do not require function derivatives
         <ol>
         <li>RootFinder::kBRENT  (default method implemented in MathCore)
         <li>RootFinder::kGSL_BISECTION
         <li>RootFinder::kGSL_FALSE_POS
         <li>RootFinder::kGSL_BRENT
         </ol>
         <li>Root Finding Algorithms using Derivatives
         <ol>
         <li>RootFinder::kGSL_NEWTON
         <li>RootFinder::kGSL_SECANT
         <li>RootFinder::kGSL_STEFFENSON
         </ol>
         </ul>
