[BioC] gcrma 1.1.3 vs. gcrma 1.1.0

[Zhijin Wu]

   The change is made in the way background parameters were estimated. The
idea is the same except we used to take local quantiles for bins of probe
affinity levels, and in 1.1.3 we used loess curve. 
  I should make available a vignette explaining that, hopefully in March.
Best,
Jean
