Base class for GSL Root-Finding algorithms for one dimensional functions which use function derivatives.
For finding the roots users should not use this class directly but instantiate the template
ROOT::Math::RootFinder class with the corresponding algorithms.
For example the ROOT::Math::RootFinder<ROOT::Math::Roots::Newton> for using the Newton algorithm.
See that class also for the documentation.
See the GSL <A HREF="http://www.gnu.org/software/gsl/manual/html_node/Root-Finding-Algorithms-using-Derivatives.html"> online manual</A> for
information on the GSL Root-Finding algorithms

usually copying is non trivial, so we make this unaccessible
