Provide custom ids for label and EditText

### Situation
Custom ids are extremely needed to use ButterKnife, to set sugar listeners, etc. No matter one uses custom layout or not, custom id will give access to view from out the AndroidFloatLabel as to ordinary view.
### Solution
* Layout ![](http://monosnap.com/image/EGMF9ZZCwqP3DTtahWVKygFK2QVWzL.png)
* Activity usage with ButterKnife sugar ![](http://monosnap.com/image/Yx6ougRvy8HGoONZLiHrGHKRU0N8Fs.png)
* or without custom layout
