Add header of Rule.isValid method
## Code Before:

from .Rule import Rule

class IsMethodsRuleExtension(Rule):

    @classmethod
    def is_regular(cls):
        return False

    @classmethod
    def is_contextfree(cls):
        return False

    @classmethod
    def is_context(cls):
        return False

    @classmethod
    def is_unrestricted(cls):
        return False
## Instruction:
Add header of Rule.isValid method
## Code After:

from .Rule import Rule


class IsMethodsRuleExtension(Rule):
    @classmethod
    def is_regular(cls):
        return False

    @classmethod
    def is_contextfree(cls):
        return False

    @classmethod
    def is_context(cls):
        return False

    @classmethod
    def is_unrestricted(cls):
        return False

    @classmethod
    def is_valid(cls):
        return False
