ShareItem requires email #94
Description
Would it be possible to not require emailaddress when calling .ShareItem()? The underlying system does not require it. Just need to not include the --emails when no email address is included; for instance if a empty array is passed in for emails?
Also, I second the request for a return value when calling ShareItem(): #91. It would be nice to have.
I'm new to github, so I apologize if I should be posting this somewhere else.
