Fetch Single Email by UID or Sequence Number

Assuming the UID is known, download a single email by UID from an IMAP mail server. C++

#include <CkImap.h>
#include <CkEmail.h>

    //  When a full email is downloaded, we would use the
    //  email.NumAttachments property in conjunction with the
    //  email.GetMailAttach* methods.
    //  However, when an email object contains only the header,
    //  we need to access the attachment info differently:
