The MEF element attributes carry extra data about elements.
Moreover, attributes (data) are inherited from containers
(fault-trees, event-trees, components, model)
by elements defined within those containers.
The element definitions can also override attributes.

The MEF attribute inheritance requires
keeping track of ancestor-containers to descendant-elements relations.
If a container's attribute changes,
its descendant-elements' attributes must be updated accordingly (a la prototype).

Required by #193

Add IFF connective to MEF and PDAG
bfffd20 
PDAG does not directly support this rare connective for analysis,
but it rewrites the MEF connective into PDAG connectives.

Limit XOR & IFF to 2 arguments in schema

These connectives are not intuitive with more than 2 args.
More reasoning: open-psa/mef#59

Make mef::Attribute a class

Even through Attribute carries arbitrary data,
it is not a dumb data.
The name and value are required to be non-empty.

Implement MEF Attribute inheritance

The interfaces are simplified to reflect the attribute inheritance.
Attribute removal and query return optional (or nullptr)
for non-existent/reachable attributes.
