Fix Ruby example
-require 'tinysplineruby'
+require 'tinyspline'
# Create a cubic spline with 7 control points in 2D using
# a clamped knot vector. This call is equivalent to:
-# spline = Tinysplineruby::BSpline.new(7, 2, 3, Tinysplineruby::CLAMPED)
-spline = Tinysplineruby::BSpline.new(7)
+# spline = Tinysplineruby::BSpline.new(7, 2, 3, TinySpline::BSpline::Clamped)
+spline = TinySpline::BSpline.new(7)
# Setup control points.
ctrlp = spline.control_points
