Bank/AR Confirmation Matcher

Matches bank and accounts-receivable confirmation responses against ledger balances on counterparty and confirmation type, and classifies each pair EXACT_MATCH, TOLERANCE_MATCH, or MISMATCH, plus confirmations with no corresponding ledger balance and ledger balances with no corresponding confirmation. The match tolerance is a policy input you declare; the default with nothing declared is 0/0 (exact match required).
