[BioC] Problem with BGandNorm() from the Agi4x44PreProcess package

Hello,

I've run into a problem that looks like the function BGandNorm() is broken because it relies on vsn as a method called by normalizeBetweenArrays, but that method has been replaced by a function normalizeVSN().

Here is some output that shows the problem:

  NORMmethod should be one of 'none', 'quantile','vsn'
