Port of Java's EnumSet collection to C#

-----------------------------------

### EnumSet

#### Overview

- Performance characteristics are similar to the [Java's EnumSet](http://docs.oracle.com/javase/7/docs/api/java/util/EnumSet.html). 

- More efficient with `Enum` types that have less than or equal to 64 values.

- Static factory methods similar to the Java version are provided: `EnumSet.Of(Bird.Stork, ...)`

#### Notes

1. `Enum` constants defined with the same value are treated as aliases:

    ```csharp

    public enum Bird { 

        BlueJay,        // 0

        Stork,          // 1

        Puffin,         // 2

        SeaParrot = 2,  // 2

        Chicken         // 3

    }

    var a = EnumSet.Of(Bird.SeaParrot);

    var b = EnumSet.Of(Bird.Puffin)

    Assert.That(a, Is.EqualTo(b)));

    ```

1. When creating an empty `EnumSet`, you must specify the type:

    ```csharp

    var a = EnumSet.Of()

    ```
