/**
* This is a simple class for sending email from within WebMacro.
* Essentially, the body of the email is a WebMacro Context object.
* The beauty of this is that you can send email from within your
* WebMacro template or from your business logic in your Java code.
* The body of the email is just a WebMacro template so you can use
* all the template functionality of WebMacro within your emails!
*
* <p>Example Usage (This all needs to be on one line in your
* template):
*
* <p>Setup your context:
*
* <p>context.put ("WebMacroEmail", new WebMacroEmail() );
*
* <p>Then, in your template:
*
* <pre>
* $WebMacroEmail.setTo("Jon Stevens", "jon@clearink.com")
* .setFrom("Mom", "mom@mom.com").setSubject("Eat dinner")
* .setTemplate("email/momEmail.wm")
* .setContext($context)
* </pre>
*
* The email/momEmail.wm template will then be parsed with the current
* Context that is stored in the
* RunData.getUser().getTemp(WebMacroService.WEBMACRO_CONTEXT)
* location. If the context does not already exist there, it will be
* created and then that will be used.
*
* <p>If you want to use this class from within your Java code all you
* have to do is something like this:
*
* <pre>
* WebMacroEmail wme = new WebMacroEmail();
* wme.setTo("Jon Stevens", "jon@clearink.com");
* wme.setFrom("Mom", "mom@mom.com").setSubject("Eat dinner");
* wme.setContext(context);
* wme.setTemplate("email/momEmail.wm")
* wme.send();
* </pre>
*
* (Note that when used within a WebMacro template, the send method
* will be called for you when WebMacro tries to convert the
* WebMacroEmail to a string by calling toString).
*
* <p>This class is just a wrapper around the SimpleEmail class.
* Thus, it uses the JavaMail API and also depends on having the
* mail.server property set in the TurbineResources.properties file.
* If you want to use this class outside of Turbine for general
* processing that is also possible by making sure to set the path to
* the TurbineResources.properties. See the
* TurbineResourceService.setPropertiesFileName() method for more
* information.
