/**
 * Quickly scans a glob pattern and returns an object with a handful of
 * useful properties, like `isGlob`, `path` (the leading non-glob, if it exists),
 * `glob` (the actual pattern), `negated` (true if the path starts with `!` but not
 * with `!(`) and `negatedExtglob` (true if the path starts with `!(`).
 *
 * ```js
 * const pm = require('picomatch');
 * console.log(pm.scan('foo/bar/*.js'));
 * { isGlob: true, input: 'foo/bar/*.js', base: 'foo/bar', glob: '*.js' }
 * ```
 * @param {String} `str`
 * @param {Object} `options`
 * @return {Object} Returns an object with tokens and regex source string.
