Minimalist exception hierarchy generator

This module lets you define an exception hierarchy quickly and simply. Here were my design goals: - minimalist interface - 80% of features in 20% of lines of code - depend only on core modules (nearly achieved) - support hierarchical error types - identify errors types by name (class) not by parsing strings - leave (possibly expensive) trace decisions to the thrower Currently, failures is implemented in under 70 lines of code. Failure objects are implemented with Class::Tiny to allow easy subclassing (see custom::failures), but Class::Tiny only requires core modules, so other than that exception, the 'core only' goal is achieved.
