Data model comparison to a11ysupport.io

This project will likely have a data model that describes tests and support information.

A similar data model was created for a11ysupport.io which has documentation on its architecture.

Some key differences between the a11ysupport data model and the one for ARIA-AT likely include:

• ARIA-AT might require two support indicators (one for support and another for quality)
• ARIA-AT might require an assertion library and tests will reference an assertion in that library
• ARIA-AT might require a different grading method
• ARIA-AT might bubble support differently
• ARIA-AT might not have the concept of core and extended browser/AT combinations
• ARIA-AT might also track the screen reader mode
