// precompile selectors so you don't have to split selector on every style sheet and every selector everytime, put in a map
// if the selector is the same as another merge them.
// if the selector has a parent or child selector then make a css prop "Selector": "full selector". should be blank if not
// can run the actual test in that case, just see if a part of the selector matches, can be cleaned up later
