Simple but handy wrappers around AES crypto methods,
hiding the boilerplate code around `crypto/aes` and `crypto/cipher`

## Example

```
	var (
		data = []byte("some sencitive data has to be protected with AES")
		key  = []byte("0123456789ABCDEF")
		iv   = []byte("qwertyuiodfghjkm")
	)

	encData, err := aescrypt.EncryptAESCBCPadded(data, key, iv)
	if err != nil {
		t.Fatal(err)
	}

	decData, err := aescrypt.DecryptAESCBCPadded(encData, key, iv)
	if err != nil {
		t.Fatal(err)
	}

	if !bytes.Equal(data, decData) {
		t.Error("decrypted data is not equal to original")
	}
```

Variables

var (
	// Panic was recovered. Will be wrapped with actual panic message.
	ErrRecovered = errors.New("recovered")

	// Data provided are invalid. Will be wrapped with actual error message.
	ErrInvalidInput = errors.New("invalid input")

Errors might be returned. They will be wrapped with stacktrace at least, of course.
