It creates `StatusPinInput` control that allows customzing its circle diameter, circle spacing and pin length. It contains a `TextInput` object that will provide the component, input text management like validation rules.
It incorporates a blinking animation when the control is focused and feedback (mouse shape changed) when hovering it.
It adds new page in sandbox to play with `StatusPinInput` control.
It adds component documentation.
Also it creates 2 new `StatusValidator` controls with their corresponding documentation:
- `StatusRegularExpressionValidator` which wraps a QML type `RegularExpressionValidator`.
- `StatusIntValidator` which wraps a QML type `IntValidator`.
