// You can force EurekaLog to generate bug report in some other format. 
// Obviously, there is no such build-in feature in EurekaLog.
// Here is a simple code that creates bug report in format of EurekaLog 6 (with less columns in call stack). 
// Naturally, you may replace the whole code by overriding TBaseLogBuilder.BuildReport method. 
// See also: https://www.eurekalog.com/downloads_extras.php
// This sample uses a combination of custom class and event handler to reach the desired goal.
