Single-chain and Cross-chain Atomic Swaps for Ethereum

Folders:

• singleswap_contracts: contracts that are used for a single swap.
• reusable_contracts: contracts that can be used multiple times (only implemented case 1).

Different types of atomic swaps:

1. Single-chain token swaps - only one contract is needed.
2. Single-chain coin/token swaps - only one contract is needed.
3. Cross-chain coin swaps - two contracts (HTLC) are needed (one per blockchain).
4. Cross-chain token swaps - two contracts (HTLC) are needed (one per blockchain).
5. Cross-chain coin/token swaps - two contracts (HTLC) are needed (one per blockchain).
