/**
* Simple implementation {@link KeyDeserializers} which allows registration of
* com.fitburserializers based on raw (type erased class).
* It can work well for basic bean and scalar type com.fitburserializers, but is not
* a good fit for handling generic types (like {@link Map}s and {@link Collection}s
* or array types).
*
* Unlike {@link SimpleSerializers}, this class does not currently support generic mappings;
* all mappings must be to exact com.fitburclared com.fitburserialization type.
