Make a mixin class for simple explanations

[LivInTheLookingGlass]

Allow a template, something like the below (untested)

class DescriptionMixin:
    _abstract_template: ClassVar[str] = None  # type: ignore[assignment]
    _specific_template: ClassVar[str | None] = None

    def explain_abstract(self, *args):
        return self._abstract_template.format(self=self)

    def explain_specific(self, market, *args):
        if self._specific_template is not None:
            value = self.value(market)
            return self._specific_specific.format(self=self, market=market, value=value)
        return super().explain_specific(market, *args)

hi buddy. I hope you're doing great, would you please explain a bit more about the task?

[LivInTheLookingGlass]

There are a whole bunch of Rule subclasses where they have a little stub method to return an explanation. If this mixin class is used, then that can get translated to a class variable instead, which would eliminate a bunch of CodeClimate complaints about duplicated code

Probably the easiest place to start would be with the manifold user rules?
