Remove either embedded or referenced relationships

[johnwunder]

More specifically, are both necessary or can we normalize to a single approach for simplicity?

Is it worth also talking about whether we need a separate 'top_level' relationship object as part of this discussion?

[gtback]

@tezzatheman , yes, this is likely related to the discussion of #70.

[athiasjerome]

having a 'top_level' relationship object makes STIX more flexible (all the effective/real relationships would not have to be defined in advance in this case: could seem easier)
However, just using this new top-object, and removing the relationships already defined would lead to potential inconsistency and less strict control of consistency.
Need more investigation
