[Bioc-devel] Changes to the SummarizedExperiment Class

There are some nice similarities in these new imaginary types. A
"GRangesFrame" is a list of dimensionally identical things (columns) and
some row meta-data (the GRanges). The SE-like object is similarly a list
of dimensionally like things (matrices, RleDataFrames, BigMatrix objects,
HDF5-backed things) with some row meta-data (a DataFrame or GRangesFrame).
Elegant? Maybe they would actually be relatives in the class tree.
I wonder if this kind of thing would be easier if we had Java-style
Interfaces or duck-typing. The "x" slot of "y" holds something that
implements this set of methods ...
Oh, and kinda apropos, the genoset class will probably go away or become an
extension to this new SE-like thing. The extra stuff that comes along with
genoset will still be available.
