Bugfix in the equals() method

Issue: #47
Pull request: #48
Contributed by @peter-gribanov

Example:

class CommandAction extends Enum
{
    const EDIT = 'edit';
}

class AccessRule extends Enum
{
    const EDIT = 'edit';
}

Expected

CommandAction::EDIT()->equals(AccessRule::EDIT()); // false

Actual

CommandAction::EDIT()->equals(AccessRule::EDIT()); // true

#4 #39 #40: new equals() method to compare enums

$enum = MyEnum::FOO();

if ($enum->equals(MyEnum::BAR())) {
    ...
}

It behaves the same as ==:

if ($enum == MyEnum::BAR()) {
    ...
}

It was added because it carries a bit more sense than == which, because it is a loose comparison, is often source of confusion (comparing objects with == is often a no-go for good reasons).

1.4.2

• #36, #37 Small phpdoc improvement for better autocompletion in IDEs

1.4.1

#21 Allow to extend the class to fetch values from somewhere else than the class constants (e.g. a database, file, …)

1.4.0

New static method values(): returns instances of the Enum class of all Enum constants (constant name in key, Enum instance in value).

MyEnum::values()

1.3.2

• Fixed #9 Ability to create invalid enum
• Fixed #13 search() is not type safe

1.3.1

Small performance enhancement.

1.3.0

A bunch of new methods were added in #5:

• $value->getKey() Returns the key of the current value on Enum
• Enum::keys() Returns the names (keys) of all constants in the Enum class
• Enum::isValid() Check if tested value is valid on enum set
• Enum::isValidKey() Check if tested key is valid on enum set
• Enum::search() Return key for searched value

The library is now PSR-4 compliant.
