updateList compares the names of oldlist and
newlist, deletes the matching elements from a copy of
oldlist, then returns the result of concatenating that list
with newlist. updateColumns updates columns of first series from same-named
columns of second series using mergeSeries(). If second series
has columns with names not found in colnames of first series, those
columns are cbind() 'ed onto first series.
