typedef boost::shared_ptr<ShapeletInterpolation> lsst::meas::algorithms::ShapeletInterpolation::Ptr

This class is an interpolator to get a Shapelet at an arbitrary position.

In addition to providing an interface to an interpolation function for Shapelets, it also measures the interpolating function.

Thus, the constructor actually just loads some parameters from a Policy file that are needed for the measurement and interpolation.

The measurement and interpolation is then done with the calculate() function.

In practice, the ShapeletInterpolation object is made by ShapeletPsf, and is used by it to implement the interpolation. I don't think there is any reason to make this object separately from a ShapeletPsf.
