* Documentation
** Improve documentation
** Use oligoData more often on documentation
** Document MAplot as function!!!
* Preprocessing
** Parallel version of PLM
** Add backgroundCorrect for FeatureSet objects
** Add normalize for FeatureSet objects
** Check accuracy of bgCorrect with 'mas' - compare against 'affy'
** Move all normalization methods from affyPLM to oligo !!!
** Add a function to show available norm/bg/summ methods !!!
** Add bg-LESN for ff !
** Consider having only backgroundCorrect(), normalize() and summarize()
* Testing
** Use unit tests
* Downstream support
** Add crlmm pipeline from SnpFeatureSet (snprma is ready, under snprma2)
** Add option to save genotype dosages
** Add Mbox (actually a function to compute M and make a boxplot - needed?) !!!
* Infrastructure
** Add scanDate to protocolData (check affy)
** Fix function for regular crlmm (instances of SnpQSet - replaced by AlleleSet - use bothStrands)
** Add selectProbes
*** by probeset name: include, exclude
*** by type: pm/mm/bg/all
*** selected fields: x/y/fix/fsetid/man_fsetid - meta_fsetid
** Add subset argument to functions that may benefit from selectProbes()
** Add oligo version to FeatureSet objs
** Optimize (par) pm<- mm<- bg<- for ff_matrix objs
