// ReflectionTypeLoadException is thrown when multiple TypeLoadExceptions may occur.  
// 
//  Specifically, when you call Module.GetTypes() this causes multiple class loads to occur.
//  If there are failures, we continue to load classes and build an array of the successfully
//  loaded classes.  We also build an array of the errors that occur.  Then we throw this exception
//  which exposes both the array of classes and the array of TypeLoadExceptions.
