// Analogue to Google's "minimessage" concept, with an alert() fallback
// mechanism. If an HTML element with "id" is found, its contents are appended
// with a message box which the user can close. If no such element is found, a
// classic JavaScript alert is popped up instead.
//
// Each message box is of class "imars_alert_box" which displays your message
// and a hyperlink "x" designed to make the box disappear. Note that it is not
// hidden, but removed from the DOM structure completely.
