get list of links meeting some filter criteria.

[monkeypants]

If there are many events for a particular products, how to get only the events that I'm interested in?

per #7, if there are many links of a type, I might want to select a filtered list,

for example:

• get all info about a link with a given URL
• all links of a given type with a given title?
• by list position?
• filter by other elements?

filter by mimeType - because I want the json credential itself, view html in the verifier, etc.
