2 arrayCGH class

For the purpose of normalization we have added several optional items to the arrayCGH objects defined in the R package GLAD, including:
a data frame with aggregated (clone-level) information, quite similar to profileCGH objects of GLAD
the name of a variable common to cloneValues and arrayValues, that can be used as an identifier for the replicates.
