/*
FinalizeCCTx is a very useful function that will properly sign both CC and normal inputs, adds normal change and the opreturn.
This allows the contract transaction functions to create the appropriate vins and vouts and have FinalizeCCTx create a properly signed transaction.
By using -addressindex=1, it allows tracking of all the CC addresses
