Building a client for the betting contract

To make it easy to find match's IDs, deploy, and invest in contracts, we need to build a UI client. So let's get started with building a client, which will have two paths, that is, the home path to deploy contracts and bet on matches and the other path to find the list of matches. We will let users deploy and bet using their own offline accounts so that the entire process of betting happens in a decentralized manner and nobody can cheat.
