Writes sequencing data out into wiggle files

  ## S4 method for signature 'AffymetrixCelSet'
writeWig(rs, design=NULL, log2.adj=TRUE, verbose=TRUE)
  ## S4 method for signature 'GRangesList'
writeWig(rs, seq.len = NULL, design=NULL, sample=20, drop.zero=TRUE, normalize=TRUE, verbose=TRUE)

`rs`	The sequencing or array data.
`design`	design matrix specifying the contrast to compute (i.e. the samples to use and what differences to take)
`log2.adj`	whether to take log2 of array intensities.
`verbose`	Whether to write progress to screen
`seq.len`	If sequencing reads need to be extended, the fragment size to be used
`sample`	At what basepair resolution to sample the genome at
`drop.zero`	Whether to write zero values to the wiggle file - TRUE saves diskspace
`normalize`	Whether to normalize each lane to its total number of reads, TRUE is suggested

A wiggle file is created for each column in the design matrix (if design is left as NULL, then a file is created for each array/lane of sequencing). The filenames are given by the column names of the design matrix, and if ending in "gz" will be written out as a gzfile.

Wiggle file(s) are created
