Planning and tracking implementation of "Connections" event stream handler

[Arlodotexe]

Background

See:

• Assessing and planning MVP event stream handler implementations #14
• Planning and tracking implementation of "Virtual" event stream handlers #17

Problem

An area map for the various implemented event stream handlers is needed.

This area map should facilitate tracking ongoing work through sub-issues regarding "virtual" event stream handlers.

The IConnections roaming interface needs to be implemented as read-only and modifiable virtual event stream handlers.

Solution

Implement the application model interfaces as event stream handlers, using IConnections as the T in IDelegable<T> to represent the roaming data manipulated by the event stream handler.

Use the code introduced in #15 as a template for implementing both read-only and modifiable versions of this virtual event stream handler.

To summarize:

• Implement the application models:
  • IModifiableConnection
  • IModifiableConnectionsCollection
  • IReadOnlyConnectionsCollection
  • IReadOnlyConnection
• As event stream handlers controlling an instance of IConnections
• Just like the code added in Initial implementation of virtual event stream handler for Images collections #15
