/**
 * Writes a data to file.
 *
 * Takes file name as first argument and config function as second.
 *
 * ```js
 * writeToFile('blog-post.md', cfg => {
 *    cfg.line('---');
 *    cfg.line('title: My blogpost');
 *    cfg.line('---');
 *    cfg.line();
 *    cfg.textFromFile('blog-post.txt');
 *    cfg.text += '// copyright by me';
 * });
 * ```
 *
 * A second argument is a config function that passes in an object for text manipulation.
 *
 * ### Config API
 *
 * * `cfg.text` - string to be written to file
 * * `cfg.textFromFile(file)` - loads a file and append its context to text
 * * `cfg.line(text)` - appends a string to a text with "\n" after
 * * `cfg.append(text)` - appends a string to a text
