Detailed Description

Description: Creates exceptions for an edm::ESHandle

Usage: When an event setup data product is requested which is not available, the edm::ESHandle<> will hold an edm::ESHandleExceptionFactory which is used to manufacture the exception which will be thrown if the ESHandle is dereferenced. Using a factory over having the exception already in the ESHandle is faster for the case where code calls Handle::isValid before dereferencing.
