Added NumberRule which checks if the value is a valid number or not

Added `MinRule` which checks if the value is greater a specific number or not
Added `MaxRule` which checks if the value is less than a specific number or not
`MinLengthRule`, `MaxLengthRule` now supports List and Map
`RequiredRule` now supports List, Map and other Data types. In case of other Data type, nullability of the value is tested
