/**
 *
 * CSS Compiler / Obfuscator / Minifier / Transpiler (PHP 5.3.0 or >)
 *
 * Stylesheet Compiler makes it possible to rename CSS class names
 * in your stylesheet, which helps reduce the size of the CSS that
 * is sent down to your users.
 * Of course, this is not particularly useful unless the class names
 * are renamed consistently in the HTML and CSS files that use the names.
 * Fortunately, you can use the Stylesheet Compiler to update the class
 * names in your CSS and to update the class names in your HTML.

 * Also it is an unique way to protect your stylesheets from theft.
 * Actually, it surly doesn't protects sheets from stealing,
 * because it's not really possible in the web technology.
 *
 * So how it works?
 * This software will transform your stylesheets in a way,
 * no one will want to modify them. They can steal it,
 * but who wants to use (and adjust) stylesheet,
 * which looks like if it's made of the worst coder in the universe?
 *
 * Got it? Try it!
 *
 * Copyright 2020 phpSoftware
 *
 * TODO
 * ALSO PARSE <style></style> TAG IN THE HTML FILE
