-wcwidth.js: A JavaScript Porting of Markus Kuhn's wcwidth() Implementation
-==========================================================================
-
-`wcwidth.js` is a simple JavaScript porting of `wcwidth()` implemented in C
-[by Markus Kuhn](http://www.cl.cam.ac.uk/~mgk25/ucs/wcwidth.c).
-
-`wcwidth()` and its string version, `wcswidth()` are defined by IEEE Std
-1002.1-2001, a.k.a. POSIX.1-2001, and return the number of columns used to
-represent the given wide character and string. Markus's implementation assumes
-the wide character given to those functions to be encoded in ISO 10646, which
-is almost true for JavaScript's characters.
-
-For convenience, `wcwidth.js` sets the getter of the property named `wcwidth`
-for the string type. You don't need to invoke a function to get the width of
-strings, but inspecting the `wcwidth` property is enough. The following code
-snippet shows how to use `wcwidth.js`:
-
-    var wcwidth = require('wcwidth')({
-        nul:         0,
-        control:     -1,
-        monkeypatch: true
-    });    // equivalent to var wcwidth = require('wcwidth')();
-
-    console.log("한글".wcwidth);    // prints 4
-    console.log("\0".wcwidth);      // prints 0
-    console.log("\t".wcwidth);      // prints -1
-
-The argument `{ nul: 0, control: -1, monkeypatch: true }` (which are the
-default values, in fact) tells `wcwidth.js` to return 0 for the NUL character
-and -1 for non-printable control characters. Setting a negative value to `nul`
-or `control` makes the `wcwidth` property set to -1 for any string that
-contains NUL or control characters respectively. If you plan to replace each
-control character with, say, `???` when printing, you can 'require'
-`wcwidth.js` as follows:
-
-    var wcwidth = require('wcwidth')({
-        control: 3
-    });    // leaving nul as 0
-
-    console.log("\t".wcwidth);    // prints 3
-    console.log("\0".wcwidth);    // prints 0
-
-The last option `monkeypatch` allows `wcwidth.js` to monkey-patch
-`String.prototype` to provide the getter `wcwidth`. Even if it is convenient to
-have a getter that looks like the native one, it is sometimes unwanted as
-adding a getter into `String.prototype` may break node.js's module system; you
-are not guaranteed to have the version your code `require`s through the getter
-if other modules you're using also depend on other versions of `wcwidth.js`
-(thanks to [timoxley](https://github.com/timoxley) for the information). By
-setting `monkeypatch` to `false`, `wcwidth.js` touches no global object and
-provides no getter but a callable method explained below.
-
-`wcwidth.js` also provides a method. Since JavaScript has no character type,
-it is meaningless to have two versions while POSIX does for C. The method also
-accepts a code value that can be obtained by the `charCodeAt()` method.
-
-    console.log(wcwidth('한'));                 // prints 2
-    console.log(wcwidth('글'.charCodeAt(0));    // prints 2
-    console.log(wcwidth('한글'));               // prints 4
