A Twitter style post length counter which can be bound to an EditText and provide callbacks when hitting a max character count.

Once bound to an EditText the characters remaining will go down as the user types. If the user goes over the max limit

you will get notified and the view will show how much they are over (-5 etc.) where you can disable UI accordingly.

**Note:** When the user has 10% or less characters remaining the text color will change to use the "exceededTextColor" 

below (Default: RED)

Normal             |  Count Exceeded
