####JSON To CSV Converter

This code can be used for generating a flat CSV file from a list of JSON Objects. The JSONFlattener will create list of key-value pairs for the generated JSON. The CSVWriter would write the key value pairs to the specified file.

For example, consider the JSON format:

[
    {
        "studentName": "Foo",
        "Age": "12",
        "subjects": [
            {
                "name": "English",
                "marks": "40"
            },
            {
                "name": "History",
                "marks": "50"
            }
        ]
    },
    {
        "studentName": "Bar",
        "Age": "12",
        "subjects": [
            {
                "name": "English",
                "marks": "40"
            },
            {
                "name": "History",
                "marks": "50"
            },
            {
                "name": "Science",
                "marks": "40"
            }
        ]
    },
    {
        "studentName": "Baz",
        "Age": "12",
        "subjects": []
    }
]

would generate a CSV as below:

Age	studentName	subjects1marks	subjects1name	subjects2marks	subjects2name	subjects3marks	subjects3name
12	Foo	40	English	50	History
12	Bar	40	English	50	History	40	Science
12	Baz

The column names would dynamically be generated based on the keys in the JSON object.
