LowerCase class

A validation rule for checking if a value contains only lowercase characters.

The LowerCase class is a concrete implementation of the FormifyRule abstract class. It is used to validate whether a value contains only lowercase characters.

This rule checks if the input value consists of lowercase letters only. If the value contains any uppercase letters or other characters, an error message is generated.
