Payment Parser

/**
 * Problem: Payment Parser
 * Difficulty: Easy
 * Topic: String parsing
 * Question: A payment is "paymentId,amount,Paying off: invoiceId" and invoices are "invoiceId,dueDate,amount". Return "<paymentId> pays off <amount> for <invoiceId> due on <dueDate>", or NOT_FOUND. (First attempt; the full 3-part version is question7.)
 * Insight: Split on commas, pull the invoice id after "Paying off: ", then look it up.
