     The main function of the package is 'vsn2'. Interesting for its
     applications are also 'predict' and the wrapper function
     'justvsn'.

     'vsn2' can be applied to objects of class 'ExpressionSet',
     'NChannelSet', 'AffyBatch' (from the 'affy' package) and 'RGList'
     (from the 'limma' package), 'matrix' and 'vector'. It returns an
     object of class 'vsn', which contains the results of fitting the
     'vsn' model to the data.

     The most common use case is that you will want to construct a new
     data object with the vsn-normalized data whose class is the same
     as that of the input data and which preserves the metadata. This
     can be achieved by


         fit = vsn2(x, ...)
         nx = predict(fit, newdata=x)

     To simplify this, there exists also a simple wrapper 'justvsn'.
