/* XRegExp 0.2.2; MIT License
By Steven Levithan <http://stevenlevithan.com>
----------
Adds support for the following regular expression features:
- Free-spacing and comments ("x" flag)
- Dot matches all ("s" flag)
- Named capture ("k" flag)
- Capture: (<name>...)
- Backreference: \k<name>
- In replacement: ${name}
- Stored at: result.name
