working network connection check

- still needs persistence for offline q’s, a’s, & r’s
- only for network & not wifi offline
- to toggle on & off network connection in emulator is F8
can add a question to then network

- elastic search classes are from the elastic search lab
can add a question or answer to network
can add question & answer to network

- handles offline question & answers & pushing it later when connected
- sort of
- only handles 1 answer at a time right now, if you add 2 answers,
it’ll only add the 2nd one - will fix this later
- ** This assumes that the main MasterList in listHandler is always up
to date (i.e. it contains all the questions on the network, which we
did not implement yet)
- Thus only adding answers to a question that is present in the
masterList (home screen) will work else it may crash b/c it can’t find
the question
