Documentation and examples

[Vadorequest]

This lib looks great when you look at the options in the source code.

But it really lacks intuitive use case examples.

For instance:

• Different types (even a link to the official doc would be useful) like https://github.com/jdorn/json-editor#format
• How to perform validation using the same schema on the model
• How to use regex for validation
• How to use default value
• Nested objects example
• How to display source code using sceditor=True
• List of editor_options
• How to use plugins https://github.com/jdorn/json-editor#specialized-string-editors
• How to have a HTML/Markdown editor through plugins
• Etc.
