recursively Object.freeze() objects and functions, works in strict mode

# deep-freeze-strict

recursively `Object.freeze()` objects.

this fork works in strict mode, so when 
freezing a function you don't get the error:
```
> (function(){ "use strict"; deepFreeze(function(){}); })();

TypeError: 'caller', 'callee', and 'arguments' properties may not be accessed on strict mode functions or the arguments objects for calls to them
```

# example

``` js
var deepFreeze = require('deep-freeze-strict');

deepFreeze(Buffer);
Buffer.x = 5;
console.log(Buffer.x === undefined);

Buffer.prototype.z = 3;
console.log(Buffer.prototype.z === undefined);
```

***

```
$ node example/deep.js
true
true
```

# methods

``` js
var deepFreeze = require('deep-freeze-strict')
```

## deepFreeze(obj)

Call `Object.freeze(obj)` recursively on all unfrozen properties of `obj` that
are functions or objects.
