Re: ISSUE-111: Create properties prov:hadLocation and prov:assumedBy

I'm not 100% sure that we need the prov:wasAssumedBy property. Assumption of
a Role is only one kind of contextualization that can occur in a provenance
document. AliceAsAuthor (with type Author) is simply a contextualization of
Alice. The rest of these are done using complementOf. I think that we should
explicitly say that role assignment is an intended use of complementOf, but
having a separate property is redundant, especially if we are trying to make
a consistent representation that requires minimal inference to understand.
