### Introduction

We have a data set of user accounts. However, some user data is missing or incomplete.

### Instructions

#### Part 1

Create a `UserAccountValidator` class, that takes in a hash to its constructor.

The hash should have the following keys.

* `:email`

* `:username`

* `:name`

Assign the values of theses keys to instance variables and create readers for them.

#### Part 2

The following conditions should `raise` an exception:

* email is missing.

* email does not contain an `@` symbol.

* username is missing.

Use the simple `raise 'message'` format for raising an exception.

#### Part 3

Create a custom error class, which inherits from `StandardError`, to handle

when emails are missing. Give the class a descriptive name.

#### Part 4

In the `runner.rb` file, use a `begin..rescue..end` code block to rescue all

`StandardError`s, and print out the details of what went wrong to the console.

#### Part 5

Write unit test for the `UserAccountValidator` class.
