Add trusted neighbour

[RaduCStefanescu]

As an user in the application I need to be able to add a list of trusted neighbours.

We need to create a new entity that links two Person entities through the relationship trusted neighbour. For now, the entity should only encapsulate minimal information:

• id of the trustee
• id of the trusted Person
• timestamp of the relationship

I would like to take this one. Person entity should be done before this?

@mischiedorian Yes. The person task #23 is open right now, you can take it if you wish

[mischiedorian]

@georgebejan, when #23 will be closed, I will take this one
