Handle append scalar in CompositeDataSetAttributes.

DataSetAttributes handles appending a scalar by creating a n-tuple array
from that scalar. CompositeDataSetAttributes needed to do the same. This
is essential to get operations like computing max(VAR) and then adding
that as point or cell data on composite dataset to work.
