Sighash class

Implements the Signature Hash algorithm.

Depending on the Sighash flags specified in SighashType, this class will remove the parts of the transaction that should not be covered by the signature and calculates the hash value to be signed.

Basically what we do is :

  1. Strip all the parts of the Transaction that should not be covered by the signature
  2. Serialize the "stripped" Transaction
  3. Calculate the double-sha256 of the serialized Transaction

Constructors
