Hi Mikhai,

Great! Nice to see such interesting to GSoC this year.

Best regards,

> network parameters to them);
>
> - Set/unset connections among network objects;
>
> - Edit the sets of the network rules.

> 3. Each object in the network will have a set of relations with other 
> objects, which are stored separately and form a network graph;
>
> 4. The whole network will have a set of rules that describes the 
> connection possibilities of different object types in the network. The 
> network will also have a set of rules that describes the influence of 
> each type of object to the state of the whole network and to the other 
> types of objects. It can also be called as a behavior of the object in

> are already implemented;
>
> 2. Complete. All data from the external source is wrapped with the 
> network proxy and the user can edit it.
