Functionality is provided to:

1. copy/move any new emails

2. copy/move a selection of emails

3. copy/move all emails

4. in the Remote Inbox to a local folder.

There are three cases for copying/moving the emails from the Remote Inbox:

1. the user is connected to the account so just copy/move the emails

2. the user is not connected to the account so connect, copy/move the emails, 
and then disconnect

3. the user is not connected to the account so connect, copy/move the emails, 
and then stay online

Objects of this type are returned from CPop3ClientMtm::InvokeAsyncFunctionL() 
when a suitable get command is requested.
