Base class for validators.

This class does nothing by default. Real validator implementations should subclass this class and implement at least the is_valid() method.

Create a new validator instance.

This method can be overridden in subclasses, e.g. to handle some values that influence the validator's behaviour.

Make sure to call the parent constructor from your custom contructor!

Checks for validity.

The return value should be true for valid values, and false otherwise.

True if the value is valid, false otherwise.
