transform json, yml to omniql/hybrids and vice versa
the initial approach consist in use the most popular way to marshall json data in every language, if almagest reach a stable release and become popular, it probably will need to use an approach similar, to easyjson https://github.com/mailru/easyjson, to improve the performance 5-6x.
anyway the most demanding task that will depends of this marshaller is probably the future swagger-omniql gateway.
