Bitcoin Script Transactions

We implement programmatically transactions that are able to submit bitcoin scripts and broadcast them onto mainnet/testnet blockchain.

1. PayToPubKey (P2PK)
   • Direct signed payment to a specified address.
2. PayToPubKeyHash (P2PKH)
   • Signed payment to the hash value of a specified address.
3. LinearEquationTransaction
   • Create a transaction that can only be redeeemed by the solution to linear equations
     • x + y = PIN_1
     • x - y = PIN_2
4. MutiSigTransaction
   • A our-party transaction that requires a bank's and 1-of-3 customer's signature to redeem

Switch mainnet/testnet in ScriptTests.java and run it as JUnit to execute the transactions
Addresses (public key) can be generated by printAddress() function
