A Serialization-Style Flattening and Description for JSON
Support JSON flattening in a long data frame way, where the nesting keys will be stored in the absolute path. It also provides an easy way to summarize the basic description of a JSON list. The idea of 'mojson' is to transform a JSON object in an absolute serialization way, which means the early key-value pairs will appear in the heading rows of the resultant data frame. 'mojson' also provides an alternative way of comparing two different JSON lists, returning the left/inner/right-join style results.
