Add examples to documentation

[Tidwell]

Currently examples are all in the readme, I'd like to condense these down with links to the new docs on the github page. This would require adding the examples to the source.

Also would like to add links to each method to the relevant steam docs page.

See the node-challonge docs for an example of how this should come together:
