module Jason is not available when appending to jsonb event store #154

When I want to append some events to the event store using the jsonb encoding, I got the following trace:

** (UndefinedFunctionError) function Jason.encode_to_iodata!/1 is undefined (module Jason is not available)
    Jason.encode_to_iodata!(%{"brand_uuid" => "MyBrand"})

You need to include the Jason library in mix.exs to use the jsonb data type:

defp deps do
  [{:jason, "~> 1.1"}]
end

That will enable the Postgrex types with JSON support.
