// right now, we only introduce one reflow per message. i.e. if you click on a message in the thread
// pane, we batch up all the changes for displaying the header pane (to, cc, attachements button, etc.)
// and we make a single pass to display them. It's critical that we maintain this one reflow per message

// presented. i.e. if it's an email address field, if you want a toggle inserted on the node in case
// of multiple email addresses, etc. We'll then use this static table to dynamically generate header view entries
// which manipulate the UI.
// When you add a header to one of these view lists you can specify the following properties:
// name: the name of the header. i.e. "to", "subject". This must be in lower case and the name of the
// header is used to help dynamically generate ids for objects in the document. (REQUIRED)
// useToggle: true if the values for this header are multiple email addresses and you want a
// a toggle icon to show a short vs. long list (DEFAULT: false)
// useShortView: (only works on some fields like From). If the field has a long presentation and a
// short presentation we'll use the short one. i.e. if you are showing the From field and you
// set this to true, we can show just "John Doe" instead of "John Doe <jdoe@netscape.net>".
// (DEFAULT: false)
//
// outputFunction: this is a method which takes a headerEntry (see the definition below) and a header value
// This allows you to provide your own methods for actually determining how the header value
// is displayed. (DEFAULT: updateHeaderValue which just sets the header value on the text node)
