add two more collections: people & venues

[elf-pavlik]

This PR simply adds two more collections to the entry point to make use case closer to datasets on real word eventing services. It also helps exemplify need discussed in #126 and currently implemented in #132

This EntryPoint should also help with driving implementation of Heracles.ts with respect to distinguishing among collections advertised in the entry point.

In future PRs I will propose various relations betweens events, people and places eg. schema:location and schema:attendee also providing use case for #134

This change is 

[elf-pavlik]

@lanthaler @alien-mcl this PR proposes what I understood that we discussed during last telecon This PR doesn't change anything in the narrative, in future PR where I will propose relations between events, people and venues I will also include extended narrative.

Looks great. Thanks Pavlik. Unless anyone objects, I'd like to merge this as soon as Pavlik fixed the minor coding style issues.

Could you please fix the indentation of @type here. And while you are at it, could you please also simplify this and the blocks below by not wrapping a single operation into an array.

Please make the indentation consistent. We have a mixture of 2 and 4 spaces in this file. I like 2 :-)
