Get the visual width of a string - the number of columns required to display it.

Some Unicode characters are [fullwidth](https://en.wikipedia.org/wiki/Halfwidth_and_fullwidth_forms) and use double the normal width. [ANSI escape codes](https://en.wikipedia.org/wiki/ANSI_escape_code) are stripped and doesn't affect the width.

|
@example
|
```
|
import stringWidth = require('string-width');
|
|
stringWidth('a');
|
//=> 1
|
|
stringWidth('古');
|
//=> 2
|
|
stringWidth('\u001B[1m古\u001B[22m');
|
//=> 2
|
```

// declare function stringWidth(string: string): number;

// export = stringWidth;
