had to make sure the getters properly calculated layout before retrieving values.
Add a Tab class to allow for better control of adding content into the tabs and managing the contents once its in there.
Use setting class to do a quick demo of the OnShow code abilities. This could be useful for things like settings pages that need to load up HW resources when they are shown but then can power them down when they are hidden.
This will allow for easy creation of "pages" that can be layed out internally and passed to different screens and cleaned up when screens are cleaned up by the screen manager
add set width and height to base elements that allow for easy resizing
Create a settings page and make it red.
Test adding 2 tabs with the Page
this currently does not do anything fantastic on simulator but it sets a strong foundation for managing multiple pages
