Change __call__ to check

[CSenshi]

As for now we have Rules as callable classes. It doesn't seem user friendly, so lets change it to use check() method, see example below for between rule:

Now: Between(18, 30)(25) After: Between(18, 30).check(25)

Hello! I am interested to contribute. @nikalosa, have you started working on this problem?

@mateuszz0000 If you are willing to contribute I'll assign this issue to you .

I'll try make it more specific

1. We need to change all Rules (in the directory 'rules_src') so that naming __call__ is changed to check

2. We need to change all of rule's doctests for example now we have something like this:

   >>> TrueBetween = Between(2, 15)
   >>> TrueBetween(23)
   False

   we need to change it to:

   >>> Between(2, 15).check(23)
   False

3. We have parent class of all rules called Rule (located at validator/rules_src/__init__.py). we need to encapsulate new method check into __call___ So now we have:

   def __call__(self, arg):
       return False

   we need to have:

   def __call__(self, arg):
       return self.check(arg)

   Good luck and don't hesitate on questions! :100:
