Registry is a singleton factory which stores
the reader/writers which are linked in
at runtime for reading non-native file formats.
<P>The RegisterDotOsgWrapperProxy can be used to automatically register
DotOsgWrappers, at runtime with the Registry. A DotOsgWrapper encapsulates
the functions that can read and write to the .osg for each osg::Object.
<P>The RegisterReaderWriterProxy can be used to automatically
register at runtime a reader/writer with the Registry.</BLOCKQUOTE>

<DD>register an fileextension alias to mapExt toExt, the later
should the the extension name of the readerwriter plugin library.
For example to map .tif files to the tiff loader, use
addExtAlias("tif","tiff") which will enable .tif to be read
by the libdb_tiff readerwriter plugin.
