Identify transferals

[bustawin]

We want to know all devices that are part of a transferal, given an id.

Although this is easy to do, as we have an id in Assign and in Receive (the two events that conform a transfer), we do not have a way for devices that we newly create in the system.

A patch (more than a solution) is to manually add an ID to a Snapshot and optionally to Assign+Receive, if we want manual IDs.

A better solution may be to create the Transfer (event?) pointing to an Assign + Receive xor a collection of Snapshot. This Transfer can have attached documents like policies.

We need to further investigate this.

Once you receive a collection of devices you need to identify by an id (receive id). This id should be insert before in devicehub or if is inexistent in the snapshot event ( website or App). This id allow the manager to link devicehub devices with own database where all id information is stored (date, donors name, agreement, price, etc). In general if users can add specifics ids when they perform events this enable the integration ( link devicehub database with custom database).
