void DeclareOptions()
 define the options (their key words) that can be set in the option string
 know options:
 PDFInterpol[ivar] <string>   Spline0, Spline1, Spline2 <default>, Spline3, Spline5, KDE  used to interpolate reference histograms
             if no variable index is given, it is valid for ALL the variables

 NSmooth           <int>    how often the input histos are smoothed
 MinNSmooth        <int>    min number of smoothing iterations, for bins with most data
 MaxNSmooth        <int>    max number of smoothing iterations, for bins with least data
 NAvEvtPerBin      <int>    minimum average number of events per PDF bin
 TransformOutput   <bool>   transform (often strongly peaked) likelihood output through sigmoid inversion
 fKDEtype          <KernelType>   type of the Kernel to use (1 is Gaussian)
 fKDEiter          <KerneIter>    number of iterations (1 --> "static KDE", 2 --> "adaptive KDE")
 fBorderMethod     <KernelBorder> the method to take care about "border" effects (1=no treatment , 2=kernel renormalization, 3=sample mirroring)
