/**
* An HTML multipart email.
*
* <p>This class is used to send HTML formatted email. A text message
* can also be set for HTML unaware email clients, such as text-based
* email clients.
*
* <p>This class also inherits from MultiPartEmail, so it is easy to
* add attachents to the email.
*
* <p>To send an email in HTML, one should create a HtmlEmail, then
* use the setFrom, addTo, etc. methods. The HTML content can be set
* with the setHtmlMsg method. The alternate text content can be set
* with setTextMsg.
*
* <p>Either the text or HTML can be omitted, in which case the "main"
* part of the multipart becomes whichever is supplied rather than a
* multipart/alternative.
