BaseSet (development version)

Now it is possible to list sets and elements that are not present in the relations but might be on the object via its factors: name_sets(), name_elements(), nElements() and nSets() gain a all argument.
Fix a problem with $<- when the length did match a slot but the name didn't.
Now it is possible to use sets and elements to subset a TidySet (but not for relations).
New dimnames() and names() functions to discover the names of the data in the slots.
Minor changes to getGAF() to improve speed.

BaseSet 0.9.0

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.
