The package implements the bnbc method for normalizing Hi-C data across samples. The name is short for band-wise normalization and batch correction. The main workhorse is the `bnbc` function. We recommend using smoothing and library size normalization first.

The package implements the `ContactGroup` class for storing multiple Hi-C contact matrices. This is most naturally done with one object per chromosome, which is ugly.

We also have functions for applying over a `ContactGroup` (`cgApply`) and working with matrix bands `band, getBandIdx`.

    data(cgEx)
    batches <- colData(cgEx)$Batch
    cgEx.cpm <- logCPM(cgEx)
    cgEx.smooth <- boxSmoother(cgEx, 5, mc.cores=1)
    cgEx.bnbc <- bnbc(cgEx.smooth, batches, 1e7, 4e4, bstart=2, nbands=4)
