More Basic Regular Expressions: Matching an Email Address

As our knowledge and experience with regular expressions grows, we can begin to match more and more generalized items, such as an email address. By coming up with the regex to match an email address, we need to use concepts such as grouping, ranges, repetition, literal characters, and more. This learning activity also expects you to have some knowledge of `grep` and `sort`.
