a ABSSeq object with element of 'counts' and 'normMethod', see the constructor functions

Given a matrix of count data, this function esitmates the size factors by selected method. It aslo provides four different methods for normalizing according to user-defined size factors, total reads, up quantile (75
a ABSDataSet object with the estimates size factors, one element per column. Use the sFactors
to show it.
