 Prepare library for the next major version 
Version 3.0 will include a few crucial deprecations. This commit adds
some soft deprecations to warn users about these changes.

Some of the biggest changes are:

* The method `validate()` will be renamed to `isValid()`.

* The method `validate()` will be repurposed to return an object with
  failures.

* It won't be possible to handle rules directly; users will need to use
  the `Validator` class to validate with any rule.

There will some more changes, but those are some of the most important
ones, and are the ones that are easy to deprecate right now.

Alpha

  • Alpha()
  • Alpha(string ...$additionalChars)

Validates whether the input contains only alphabetic characters. This is similar to Alnum, but it does not allow numbers.

v::alpha()->isValid('some name'); // false
v::alpha(' ')->isValid('some name'); // true
v::alpha()->isValid('Cedric-Fabian'); // false
v::alpha('-')->isValid('Cedric-Fabian'); // true
v::alpha('-', '\'')->isValid('\'s-Gravenhage'); // true

You can restrict case using the Lowercase and Uppercase rules.

v::alpha()->uppercase()->isValid('example'); // false
