PHP compatibility warning (PHP >= 7.0)

[estevao90]

I found a small issue that affects the PHP compatibility. It's a warning:

FILE: src/Rules/Numeric.php
----------------------------------------------------------------------
FOUND 0 ERRORS AND 1 WARNING AFFECTING 1 LINE
----------------------------------------------------------------------
 17 | WARNING | 'numeric' is a soft reserved keyword as of PHP
    |         | version 7.0 and should not be used to name a class,

    |         | declaration)
