C# Класс CrestSharp.Infrastructure.CrestJsonContractResolver

This contract resolver gets only private fields through the whole class hierarchy for ICrestObject subclasses. This is unfortunately needed, because JSON.NET always reads a _property_ when it writes it with a custom JsonConverter. That means a lazy load of an object would trigger an infinite loop of loading the same object. Therefor we use this to read/write the backing fields instead of the properties which doesn't trigger the lazy loading.
