distanceToSp

If the optimal view is known, we can use the distance between a given plane
and the optimal one as a proxy to diagnose the performance of the guided tour.

Projection pursuit is used to find interesting low-dimensional
projections of high-dimensional data by optimizing an index over all
possible projections. The 'spinebil' package contains methods to evaluate
the performance of projection pursuit index functions using tour methods.
A paper describing the methods can be found at <doi:10.1007/s00180-020-00954-8>.
