Create Network Generation final package

[bokobza]

This corresponds to item 5 in User Flow in https://github.com/stratisproject/FederatedSidechains/issues/79.

Dependencies: https://github.com/stratisproject/FederatedSidechains/issues/80, https://github.com/stratisproject/FederatedSidechains/issues/81, https://github.com/stratisproject/FederatedSidechains/issues/83.

At the end of the Network Generation process, we should have:

• projects created for Networks and the FederationGatewayD
• compiled dlls of the above projects
• config files for FederationGatewayD
• a script to start the 2 nodes each member needs to run
• some extra documentation (how to).
