RNASeqAssay added
Merge branch 'master' of github.com:RGLab/SingleCellAssay
Made the initialize method for the SingleCellAssay class use data.table.
Not significantly faster since indexing still needs to occur for deduplication. The whole thing should probably be rewritten to be more efficient. We ought to have a constructor that takes separate cellData, featureData and expression data tables / frames. This is how the RNAseq data is provided and we are merging it only to feed it into the constructor and then separate it out again. This is pretty wasteful and slow.
