/**
* A file we are sending or receiving
*
* For sending, we have sub types of Mail (Netmail/Echomail) and Files (File & TIC)
* When sending, we can queue up a list of items, and mark one active (the one being sent) at a time.
*
* + Netmail/Echomail/TIC
* + name is the hex ID of the youngest item in the mail bundle
* + size is dynamically calculated based on the size of the bundle
* + mtime is dynamically calculated, based on the age of the youngest item
* + sendas (nameas) is name + [.pkt|.tic]
*
* = Need to know the DB ID for the items being sent, so as to mark them sent
*
* + Files
* + name is the full path file name
* + size is the file size
* + mtime is the file mtime
* + sendas (nameas) is filename only
*
* For receiving, we just received files, and based on its name, we determine if it is a mail/file/tic or request
* When receiving, we receive one file at a time, and our list has the list of files we've received
*
* + name our name (including path) with the address ID prefixed of the sender
* + size is advised to us by the remote
* + mtime is advised to us by the remote
* + receiveas (nameas) advised to us by the remote
*
* @property string $name The (full path) name of the file we are sending or receiving
* @property string $nameas The name as we communicate with the remote
* @property int $mtime The date/time timestamp of the item we are sending or receiving
* @property int $pos Our counter of where we have read to when sending
* @property int $size The size of the item we are sending or receiving
