An easier and safer to use interface for good, cryptographically secure, random.

## Use

`CBHRandom` provides class methods for producing random data of fixed and variable length with bounding constraints.

#### Example:

Generate a random `NSUInteger`:

```objective-c

NSUInteger randInt = [CBHRandom randomUnsignedInteger];

```

Generate a random `NSUInteger` less then 128 inclusive:

```objective-c

NSUInteger randInt = [CBHRandom randomUnsignedIntegerWithBound:128];

```

Generate a random `NSUInteger` between 64 and 128 inclusive:

```objective-c

NSUInteger randInt = [CBHRandom randomIntegerBetweenLower:64 andUpperBound:128];

```

Shuffling an Array:

```objective-c

NSArray *array = @[@1, @2, @3, @4, @5];

NSArray *shuffledArray = [array arrayByShuffling];

```

Shuffling an Array in-place:

```objective-c

NSMutableArray *array = [NSMutableArray arrayWithObjects:@1, @2, @3, @4, @5, nil];

[array shuffle];

```

Requesting a random object from Array:

```objective-c

NSArray *array = @[@1, @2, @3, @4, @5];

NSNumber *number = [array randomObject];

```
