/**
* This class has one method used for sending a MIME email the same way that
* PHP's standard mail function does, except the 3rd argument must be a stream
* thereby reducing the memory overhead need to send large attachments
*
* These functions are best when used with large files that cause
* memory capacity to be exceeded
