One-dimensional Root-Finding

Classes implementing algorithms for finding the roots of a one-dimensional function.

Various implementation esists in MathCore and MathMore The user interacts with a proxy class ROOT::Math::RootFinder which creates behing the chosen algorithms which are implemented using the ROOT::Math::IRootFinderMethod interface
