IVS-157 single component

[aothms]

Implementation is trivial, but depends on networkx. Test files include also the TAS mirror image, will be moved later after review.

A little nitpicking from my side;

• Already fixed, but the naming of the feature file (the actual .feature filename) was not consistent with the others (a hyphen instead of an underscore after the rulecode); the protocol checks spotted this.
• The versioning tag was @version2 (also fixed). If this was intentional, feel free to revert of course.
• The presnet rule-tag is @GEM. The other @BRP(001) rule has both @GEM and @BRP tags. I'm not sure whether we should have both tags here as well.

Test files include also the TAS mirror image, will be moved later after review.

When I remove these files manually, the tests pass :-)

[Ghesselink]

I've also deployed locally and tested the platform and it behaves as expected (i.e. failing testfiles are failing, passing are activated/green).

but depends on networkx.
