More Regular Expressions: Using Lookarounds to Parse Data

While using regular expressions, lookarounds allow us to create zero-width boundaries where the boundaries are also regular expressions. This will enable us to ensure that our primary expression either begins or ends with the provided lookaround or does _not_ begin or end with the provided lookaround. The expression in the lookaround is matched, but not captured, so the resulting match is only the non-lookaround text. This allows us to fine-tune our expressions and ensure we're only matching what we want.
