mapping a yaml field to an object in code has always been a stateless operation. You could still pass state by using the `setContext` function of the YAMLIO object, but this represented global state for the entire yaml input. In order to have context-sensitive state, it is necessary to pass this state in at the granularity of an individual mapping. This patch adds support for this type of context-sensitive state. You simply pass an additional argument of type T to the `mapRequired` or `mapOptional` functions, and provided you have specialized a `MappingContextTraits<U, T>` class with the appropriate mapping function, you can pass this context into the mapping function.
