Detailed Description

class Wombat::MamdaQuoteChecker;

MamdaQuoteChecker is a class that provides quotes sanity checking by periodically requesting snapshots of the quotes from the publisher and comparing that with an quotes being maintained in real time. This class is purely for testing purposes, to test for possible configuration or programming errors in the quotes publisher and in MAMDA quotes management code.

The developer registers a handler that contains callbacks for successful, inconclusive and failure events. The developer also provides an interval representing the frequency of the snapshot checks. The first check will take place at some random point in time between zero and the interval.
