* Transforms a basic regular expression into a random string satisfying the expression.

*
* Regex delimiters '/.../' and begin/end markers '^...$' are ignored.
*
* Only supports a small subset of the regex syntax. For instance,
* unicode, negated classes, unbouned ranges, subpatterns, back references,
* assertions, recursive patterns, and comments are not supported. Escaping
* support is extremely fragile.
*
* This method is also VERY slow. Use it only when no other formatter
* can generate the fake data you want. For instance, prefer calling
* `$faker->email` rather than `regexify` with the previous regular
* expression.
*
* Also note than `bothify` can probably do most of what this method does,
* but much faster. For instance, for a dummy email generation, try
* `$faker->bothify('?????????@???.???')`.
