the problem is that we are facing another type of dependency here,
something like a "runtime dependency".

by the moment of the development the developer DOES NOT KNOW will his 
application depend on the 'ssl' or not.
therefore he can not specify a dep.

however, we know for sure how to determine the very same dep LATER ON.
it is clear that 'ranch's dependency on 'ssl' is implied by the deps of 
a top-application.
so that i propose a clear unambiguous algorithmic way how to alter some 
deps within the deps-tree according to the deps of the top-app.
