Component guideline test

[levithomason]

There should be a test that ensures a component adheres to the guidelines. We should then loop through all the components on stardust and run the test against them.

Tests

• className is inherited.
• If the underlying class name follows ui <component> format, className is inherited between ui and <component.
• If the underlying class name does not include ui, className is inherited before the component class. Example, fields only have a field class, inheritance is <className> field.
• props are spread on the underlying element.
