Method cache

src/main/java/org/htmlunit/Cache.java:202–206

Caches the parsed version of the specified CSS snippet. We key the cache based on CSS snippets (rather than requests and responses as is done above) because a) this allows us to cache inline CSS, b) CSS is extremely expensive to parse, so we want to avoid it as much as possible, c) CSS files aren't

     * Truncates the cache to the maximal number of entries.
