Create the Network Generation tool interface

[bokobza]

Create an executable that a user can run and be presented with a web page to populate with a bunch of fields. This task is done when

• a web page is fully designed and contains fields to fill + a "generate" button
• it is packaged, distributable and runnable.

Corresponds to 1 and 2 of the User Flow in https://github.com/stratisproject/FederatedSidechains/issues/79.
