...
Add a unit test for providing an alternate rules loader that also
demonstrates how users can define sub-classes that may want to extend
the falco rules syntax.
This test creates a test rules reader/collector/compiler that supports
top-level objects "test_object". The reader reads them and saves them
in the collector. The compiler iterates over all test_objects and puts
the property values into a single set<string>.

In order to allow the user to supply environment variables in standard

to cover this new functionality

...
* address reviewers feedback
* improve clarity around new -A and -i behavior
* additional cleanup (e.g. use generic set operations only)
* extend unit tests
