Animatable checkbox: Default checked and unchecked icon

[JakeLin]

Using path to avoid image assets?

What's the difference with the existing images in CheckboxDesignable?

  public func configCheckBoxCheckedImage() {
    guard let unwrappedCheckedImage = checkedImage else {
      return
    }

    setBackgroundImage(unwrappedCheckedImage, forState: .Selected)
    setBackgroundImage(unwrappedCheckedImage, forState: [.Selected, .Highlighted])
  }

  public func configCheckBoxUncheckedImage() {
    guard let unwrappedUncheckedImage = uncheckedImage else {
      return
    }

    setBackgroundImage(unwrappedUncheckedImage, forState: .Normal)
  }

@tbaranes To avoid including any asset in IBAnimtable, the user need to have two images when they use AnimatableCheckbox. And need to set both checkedImage and uncheckedImage properties to the image assets.

Do you think it is useful to provide default tick and cross signs in paths? Then the user doesn't need to provide images any more. The good part of the path is they can animate from one state to another. Something like http://cloudcannon.com/deconstructions/2014/12/05/material-design-delightful-details.html . But in our case, it will animate a tick to cross and vice verse like https://www.youtube.com/watch?v=56GzZ8PYL68

I see. Yeah, that can be really useful for prototyping (like predefined{Color,Gradient}. I'm just not sure to includes specific images directly in IBAnimatable, if we do the #67, instead of default images, we can have directly a custom animation which can include default value.

Anyway, I now understand that issue 😆

@tbaranes #67 are related, and maybe we can merge them into one issue. We can provide a path for checkbox and some default animations. And allow the user set the color and animation type.

Sounds cool 👍
