spline::SplineGenerator numeric::interpolation::spline_from_file ( std::string const &  filename,
platform::Real const &  bin_size 
)

given a file, return a 2D spline

read in a file, read out a spline. The file should be tab separated, and have two lines The first field of one line should be "x_axis", the next fields should be the x values of the points for the spline The first field of the other line should be "y_axis", the next fields should be the y values for the points on the spline For an example, see "scoring/constraints/epr_distance_potential.histogram"
