%description
Decompose a time series into seasonal, trend, and remainder components
using an implementation of Seasonal Decomposition of Time Series by Loess
(STL) that provides several enhancements over the STL method in the stats
package.  These enhancements include handling missing values, providing
higher order (quadratic) loess smoothing with automated parameter choices,
frequency component smoothing beyond the seasonal and trend components,
and some basic plot methods for diagnostics.
