Finds if a string is inside an array of strings
Is it faster to check if a full selector matches an element or if individual selectors match? One matching selector is FASTER than many by a factor of x3 (which only gets worse as more selectors are searched, > 1000 is like x7) HOWEVER, if you need to determine WHICH selectors match, that requires you to do the individual search, at which point your search is actually a quarter worse than just doing the individual search at the start. nullifying much of the savings. If a match will be RARE, it could make sense to do the full string. however, if a match is common, I'd just stick with the individual matching from the start.
