>From the last dev discussion I thought we had decided to not provide
(at least immediately) any actual replacement for SparseDataFrame class
(in the sense of supporting 2d sparse structures, i.e. skipping
columns). Unless I misunderstood, this is probably the change that
users (of sparse structures) should be most aware.

(On the other hand, it is true that in most cases transposing the
DataFrame will probably still allow for exactly the same data structure
...)
