Could this be the deal that saves the euro? Eurozone leaders have REACHED agreement on a three-part package to end the debt crisis. Cutting Greece's debts. Strengthening Europe's banks. And beefing up the bailout fund. The deal didn't come easy -- leaders wrangled until the early hours of the morning, trying to persuade banks to accept a big write-down on their holdings. The result - a 50-percent cut. But other parts of the deal - like exactly how the bailout fund will be "leveraged" - remain uncertain.
