Detailed Description

Performs interpolation using GSL (GNU Scientific Library)

On construction takes in vectors x and y, to be interpolated. These are intepreted as function values y(x) at descrete points x. x and y dimensions must match. Given new x', will return y(x') based on interpolation. NOTE: Interpolates, but does NOT extrapolate! Everything outside the region (xmin,xmax) from initial input will be zero. It may use any interpolation method provided by GSL library. See Interpolator::Method for list of options. By default, cspline (cubic b-spline) method is used. Note: gsl function takes pointers to x and y data. Therefore, vectors x and y should outlive the Interp object
