+ * Copied from Densaugeo/JSON-String-Splitter
+ *
+ * Split concatenated JSON strings
+ * Accepts a string consisting of one or more valid JSON substrings and splits it. Any remaining string after the end of the last complete JSON substring is returned in the 'remainder' field.
+ * Passing in invalid JSON can result in garbage output
+ *
+ * @param {string} string The string to look for JSON in
+ * @returns {{ jsons: string[], remainder: '' }}

+ * @example
+ * var splitter = require('json-string-splitter');
+ *
+ * var pieces = splitter('{"foo":"bar"}{"more":"json"}{"partial":"json"');
+ *
+ * console.log(pieces.jsons[0]); // '{"foo":"bar"}'
+ * console.log(pieces.jsons[1]); // '{"more":"json"}'
+ * console.log(pieces.remainder); // '{"partial":"json"'
