- \class Uncompressor
-
- \brief The Uncompressor class is a base class for classes that
- know how to uncompress a certain kind of compressed file.
-
- The uncompressor contains a list of the filename extensions
- of the file types that the uncompressor knows how to uncompress.
-
- It maintains a static list of all the instances of Uncompressor
- that have been created. It also has a static function for searching
- that list to find the uncompressor to use for uncompressing a file
- with a certain extension.
- */
-
-/*!
- The constructor takes a list of filename extensions, which it
- copies and saves internally. This uncompressor is prepended
- to the stack list.

- This function searches the static list of uncompressors to find the
