BUG FIX principal_curve(): avoid division by zero when the initial principal curve
has already converged.
BUG FIX project_to_curve(): set dimension names of outputted s correctly.
DOCUMENTATION: Added cran-comments.md and revdep to repository.
MINOR CHANGE: Removed adjust_range(); use grDevices::extendrange() instead.
TESTING start_circle(): Added unit tests.
BUG FIX start_circle(): Make sure circle is centered and scaled correctly.
MINOR CHANGE: Move smoother functions from inside principal_curve() to
a list smoother_functions.
TESTING smoother_functions: Added tests to ensure each of the smoother
functions work correctly.
SPEED UP project_to_curve(): Significantly speed up this function by not
allocation objects that don't need allocation, and pre-allocating objects
that do.
SPEED UP principal_curve(): Added approx_points parameter. This allows
approximation of the curve between smoothing and projection, to ensure
principal_curve() scales well to higher numbers of samples.
