Release v0.1.5

Basic support for JSON

Handles #8

Works on files which look like this:

{"a":1, "b":2.0, "c":false, "d":"4"}
{"a":-10, "b":-3.5, "c":true, "d":"4"}
{"a":2, "b":0.6, "c":false, "d":"text"}
{"a":1, "b":2.0, "c":false, "d":"4"}
{"a":7, "b":-3.5, "c":true, "d":"4"}
{"a":1, "b":0.6, "c":false, "d":"text"}
Does not work on files which are a single json array:

[
{"a":1, "b":2.0, "c":false, "d":"4"},
{"a":-10, "b":-3.5, "c":true, "d":"4"},
{"a":2, "b":0.6, "c":false, "d":"text"}
]
