A demo Elixir program that uses `Structs` as `Data Transfer Objects`,
and `Agents` to persist state between precesses.
Challenge 5 of Ignite Elixir, a bootcamp by Rocket Seat.
```bash
# Create new Elixir project
$ mix new project_name
# Intall dependencies
$ mix deps.get
# Generate linter config
$ mix credo gen.config
# Run linter
$ mix credo --strict
# Start your project as an Interactive Elixir session
$ iex -S mix
# Run tests
$ mix test
```
Expected behavior:
```elixir
> Flightex.create_user(params)
{:ok, user_id}
> Flightex.create_booking(user_id, params)
{:ok, booking_id}
> Flightex.create_booking(invalid_user_id, params)
{:error, "User not found"}
> Flightex.get_booking(booking_id)
{:ok, %Booking{...}}
> Flightex.get_booking(invalid_booking_id)
{:error, "Flight Booking not found"}
```
Naive Date Time (Date-time without timezone):
```elixir
> NaiveDateTime.from_iso8601("2015-01-23 23:50:07")
{:ok, ~N[2015-01-23 23:50:07]}
> NaiveDateTime.from_iso8601!("2015-01-23 23:50:07")
~N[2015-01-23 23:50:07]
> dt = %DateTime{year: 2000, month: 2, day: 29, zone_abbr: "CET",
> hour: 23, minute: 0, second: 7, microsecond: {0, 0},
> utc_offset: 3600, std_offset: 0, time_zone: "Europe/Warsaw"}
#DateTime<2000-02-29 23:00:07+01:00 CET Europe/Warsaw>
> NaiveDateTime.to_erl(dt)
{{2000, 2, 29}, {23, 0, 7}}
```
UUID4 validation:
```elixir
> {:ok, [{:uuid, valid_uuid} | _tails]} = UUID.uuid4() |> UUID.info()
{:ok,
[
uuid: "52224694-3cee-48f9-938c-ab99830c2881",
binary: <<82, 34, 70, 148, 60, 238, 72, 249, 147, 140, 171, 153, 131, 12, 40,
129>>,
type: :default,
version: 4,
variant: :rfc4122
]}
> valid_uuid
"52224694-3cee-48f9-938c-ab99830c2881"
> {:error, message} = "SOFUNKY" |> UUID.info()
{:error, "Invalid argument; Not a valid UUID: sofunky"}
```
User Agent and Creator:
```elixir
> Flightex.start_agents()
> user_params = Flightex.Factory.build(:user)
> {:ok, user_id} = Flightex.create_user(user_params)
{:ok, "9a68c5da-2f51-4e5e-a2b8-21b7dee48105"}
> Flightex.update_user(user_id, user_params)
{:ok, "9a68c5da-2f51-4e5e-a2b8-21b7dee48105"}
> Flightex.update_user("SOFUNKY", user_params)
{:error, "User not found."}
> Flightex.get_user(user_id)
{:ok,
%Flightex.Users.User{
cpf: "1234567",

{:error, "User not found."}
> Flightex.get_users
%{

Booking Agent and Creator:
