Self-Contained JSON file format

[InnocentBug]

Description

The SDK can produce fully self-contained JSON string for node graphs. Such a node graph does not contain any UUID reference (self-contained) and can be super helpful for users if they want to store their work in a JSON file before uploading it to CRIPT.

@bearmit expressed that he would like this feature.

Changes

Also added a hint about using kwargs to beautify JSON strings into the documentation.

Tests

A test is included to ensures that self-containing JSON can be parsed by cript.load_nodes_from_json.
