name_sets(), name_elements(), nElements() and nSets() gain a all argument.$<- when the length did match a slot but the name didn't.dimnames() and names() functions to discover the names of the data in
the slots.getGAF() to improve speed.tidy() now defaults to tidySet().
New function union_closed().
Make more robust the code to unwanted dimensions drops.
power_set() returns also the sets of size 1 and have better names by default.
Extractors [, $, [[ and setters [<-, $<-, [[<- now work for
TidySets:
i indicates rows,j either "relations", "sets" or "elements"k the columns of the slot.However TS[["A"]] extracts set "A" and replacing it via [[<- will remove
it.
Completion of $ works.
length() returns the number of sets (to complete ncol and nrow).
lengths() returns the number of relations for each set.
