Query factory

Implements

launcher.getFactory().Query().createQuery().map...
launcher.getFactory().Query().createQuery(anInput).map...

This PR is based on #1090. I will rebase it after #1090 is finished and merged.

rebase?

Interesting. By the way: what does an bound and empty query return by default? nothing or all children?

what does an bound and empty query return by default?

I have added tests for this contract.

• Bound query returns bound element
• Unbound or null bound query returns no element

Super.
Would you also add one or two sentences and remove the remaining new CtQueryImpl() in filters.md?

OK now we catch doc errors again in Travis, but it's a nightmare to locate them.

Seems to be done from my side
