/**
 * A simple implementation of mail messages.  Intended to illustrate
 * a basic, but correct, solution for assignment 1 of CS152 99F.
 *
 * Right now, includes only one primary recipient and no carbon-copied
 * recipients.  Also ignores many common header fields.  All email
 * addresses should be of the form name@host.  Names should not include
 * quotation marks.  Of all the components you can set and get, only
 * dates can be null.
 *
 * May eventually be expanded to include that additional information.
