/**
* Give a warm greeting to our friendly user
* Email registration
*
* This sample action shows some basic ways of doing output in an action
* class.
* There are four cases where we're called:
*
* Action classes have several output methods that they override from
* the parent class.
* 1. GET, no arguments. Initial registration; ask for an email address.
* 2. POST, email address argument. Initial registration; send an email to confirm.
* 3. GET, code argument. Confirming an invitation or a registration; look them up,
* create the relevant user if possible, login as that user, and
* show a password-entry form.
* 4. POST, password argument. After confirmation, set the password for the new
* user, and redirect to a registration complete action with some instructions.
