Should generate file_names and file_paths (maybe with a option to chose either Names With Mixed Casing, Spaces and operators, lowercase_names_with_underscore or both)

file_paths additionaly might receive an option windows or unix to define the path style

Eg: instead of

iex> Burette.Calendar.future           
%DateTime{year: 2017}
iex> Burette.Calendar.future year: 2050
%DateTime{year: 2050}

do

iex> Burette.Calendar.future           
%DateTime{year: 2017}
iex> Burette.Calendar.future year: 1..10
%DateTime{year: 2022}

As most tests that use relative past/future use so to check that the input date is inside a certain range, eg:

test "only adults can create accounts" do
  young_birth_date = DateTime.to_date(Burette.Calendar.past(year: 12..17))
  adult_birth_date = DateTime.to_date(Burette.Calendar.past(year: 18..32))

  refute Account.old_enough?(young_birth_date)
  assert Account.old_enough?(adult_birth_date)
end

I've had some (albeit rare) collisions. As a test, i tried to run the username generator a few times like this:

Enum.reduce(1..1_000, MapSet.new(), fn _, acc ->
  MapSet.put(acc, Burette.Internet.username())
end)

I explicitly used a relatively small set (because most of the times test suites will not add over a thousand of test users; will they ?) and the results were actually pretty bad...

results = Enum.map(1..500, fn _ ->
  xs = Enum.reduce(1..1_000, MapSet.new(), fn _, acc ->
    MapSet.put(acc, Burette.Internet.username())
  end)

  MapSet.size(xs)
end)

IO.puts "Median: #{Math.median(results)}"

Median: 980.0

If we increase the input amount from 1_000 to 2_500, it get worse

Median: 2388.0

This can only means one thing, Burette.Internet needs more username patterns and username words to reduce collision chance

Lexicon is useful to build dictionaries of possibilities and someone could find use for it on a prod environment (without needing the compile time overhead of the full Burette package), for this reason it makes sense to make the lexicon an independent repository/library/package
