Unity_UI-RespectMobileSafeArea

//reference: https://youtu.be/VprqsEsFb5w
//adapted and optimized by me: https://github.com/Luanrobs

//simple and elegant script that has the sole purpose of making the child objects respect the safeArea of each cell model
//it is possible to better visualize it in action using simulator, especially useful in models with notch
