/**
* Use this utility to send email from Grouper. Many of these methods are new as of v2.5.47+. The original "set" methods have been there since v1.4+
* Configured from the smtp external system:
* https://spaces.at.internet2.edu/display/Grouper/Grouper+smtp+external+system
* Unlike most other method chaining classes, you need to call assignRunAsRoot(true) before adding subject and group lookups if you dont want to check security
* Sample call to send an email:
*
* new GrouperEmail().setTo("[email protected]").setBody("email body").setSubject("email subject").send();
*
*
* Send an email to a subject:
*
* new GrouperEmail().assignRunAsRoot(true).addSubjectIdentifierToSendTo("mySourceId", "someNetId").setBody("email body").setSubject("email subject").send();
*
*
* Sample call to send an email:
*
* new GrouperEmail().assignRunAsRoot(true).addGroupToSendTo("a:b:c").setBody("email body").setSubject("email subject").send();
*
*
* You need to configure email address in your person subject source to send to subjects
* At least one "to" address is required.
* To debug emails, set debug to true in the smtp external system, and set the log4j.properties entry:
*
* log4j.logger.edu.internet2.middleware.grouper.util.GrouperEmail = DEBUG
