Initial patch leverages the existing tag/exclude framework for tag/exclude
faceting. Runs but needs tests.

> Adding tag/exclude functionality to the ExpandComponent would allow it to
> operate independently of the CollapsingQParserPlugin. For example:
> {code}
> q=*:*&fq={!tag=parent}type=parent&expand=true&expand.field=group_id&expand.exclude=parent
> {code}
> The query above searches all documents limiting the results to type=parent.
> So the main result would contain only parent documents.
> The expand component then excludes the type=parent filter and expands the
> groups based on the group_id field.
> Using this approach the main search result will contain only documents with
> type=parent and the expanded results will display the child documents for the
> group.
