wish: docs for saml.getLogoutUrl and saml.getLogoutResponseUrl

[sibelius]

We have two methods to generate a logout request and a logout response:

• saml.getLogoutUrl
• saml.getLogoutResponseUrl

when should we use each of them?

I see that getLogoutResponseUrl uses an id of logoutUrl

is there any way to pass a callback logout url to logout request?

You'll find both these methods are called from strategy.js. Do those examples answer your questions:

https://github.com/bergie/passport-saml/blob/master/lib/passport-saml/strategy.js#L49
https://github.com/bergie/passport-saml/blob/master/lib/passport-saml/strategy.js#L104

It would be helpful to have some JSdoc right in saml.js that explains right there how the functions are used.
