Shuffle function for Unity, primarily intended for object pools.

Shuffle.cs

/// <summary>
/// This is used for when we're working with an object pool that has
/// a variety of randomized objects and is not seeing frequent heavy use.
/// 
/// For cases where the object pool has randomized elements (such as
/// enemies with different stats), working with that pool has the
/// possibility of just returning the same exact object every time we
/// request an object from it. For random spawns, we don't want this.
/// 
/// Shuffle is used to randomly reorder an object pool so that this doesn't
/// happen.

/// <param name="list">The object pool to reorder.</param>
/// <returns>Reordered object pool.</returns>
