- support move insert/set and emplace insertion.
These adjustments can be used for improved memory efficiency, and
allow hash tables of non-copyable objects (eg, std::unique_ptr).
- extend special HashTable output treatment to include pointer-like
objects such as autoPtr and unique_ptr.
ENH: HashTable::at() method with checking. Fatal if entry does not exist.
- use succincter method names that more closely resemble dictionary
and HashTable method names. This improves method name consistency
between classes and also requires less typing effort:
args.found(optName) vs. args.optionFound(optName)
args.readIfPresent(..) vs. args.optionReadIfPresent(..)
...
args.opt<scalar>(optName) vs. args.optionRead<scalar>(optName)
args.read<scalar>(index) vs. args.argRead<scalar>(index)
- the older method names forms have been retained for code compatibility,
but are now deprecated
