c99f3818b7Since the library doesn't need to give support to version 5.4 or less of PHP using variadics in the constructor of "AbstractFilterRule" seems better than doing the whole validation. This commit will also apply the contribution guidelines to "AbstractFilterRule" and use a better naming for it. Signed-off-by: Henrique Moody <henriquemoody@gmail.com>
