##Usage

Using CalculatorKeyboard is quite simple. First you need to import the Framework

import CalculatorKeyboard

Then instantiate the view and apply it to a text input (UITextField or UITextView).

let calcInputView = CalculatorKeyboard(frame: frame)
calcInputView.delegate = self
textField.inputView = calcInputView

CalculatorKeyboard uses a delegate to report back the values. That way, you have the flexibility to format the text the way you want before displaying to the user.

func calculator(calculator: CalculatorKeyboard, didChangeValue value: String) {
	valueTextField.text = value
}

// Show/Hide decimal button in keyboard. When hidden, the decimal input begin from the least
