JSN - Fast low allocation JSON library

Design

This libary is designed as a set of seperate functions to extract data and mutate JSON. All functions are focused on keeping allocations to a minimum and be as fast as possible. The functions don't validate the JSON a seperate Validate function does that.

The JSON parsing algo processes each object {} or array [] in a bottom up way where once the end of the array or object is found only then the keys within it are parsed from the top down.

{"id":1,"posts": [{"title":"PT1-1","description":"PD1-1"}], "full_name":"FN1","email":"E1" }
