What is it good for?

[jabbalaci]

At the beginning of the README, state clearly what it is good for.

Now you have this:

"""
ndjson
Support for ndjson. Plain and simple.
"""

But what is ndjson? It's a recursive description.

This page describes the ndjson format, also called Newline delimited JSON. NDJSON is a convenient format for storing or streaming structured data that may be processed one record at a time. It works well with unix-style text processing tools and shell pipelines. It's a great format for log files. It's also a flexible format for passing messages between cooperating processes.

1. Line Separator is '\n'
   This means '\r\n' is also supported because trailing white space is ignored when parsing JSON values.
2. Each Line is a Valid JSON Value
   The most common values will be objects or arrays, but any JSON value is permitted. See json.org for more information about JSON values.
