Include more detail on the pipe operator about website

[lpil]

Hi! Thanks for the report.

The book says "This is similar in functionality to the same operator in Elixir or F#.", not that it has the same functionality. I think we could expand upon the pipe operator though, breaking it into its own page with more detail.

@lpil Want me to take a shot at this?

I would attempt to cover:

• piping vs nesting function calls (for starters)
• default position vs using the _ (discard/placeholder/insert/wildcard-operator?) operator
• 2 brief examples piping into anon functions and piping into case

Anything else?

That sounds fab! Thank you
