* JSMin.php - modified PHP implementation of Douglas Crockford's JSMin.
*
* <code>

* </code>
*
* This is a modified port of jsmin.c. Improvements:
*
* Does not choke on some regexp literals containing quote characters. E.g. /'/
*
* Spaces are preserved after some add/sub operators, so they are not mistakenly
* converted to post-inc/dec. E.g. a + ++b -> a+ ++b
*
* Preserves multi-line comments that begin with /*!
*
* PHP 5 or higher is required.

* headers, allowing shared caches to cache the output. (default true)
*
* 'quiet' : set to true to have serve() return an array rather than sending
* any headers/output (default false)
*
* 'encodeOutput' : set to false to disable content encoding, and not send
* the Vary header (default true)
*
* 'encodeMethod' : generally you should let this be determined by
* HTTP_Encoder (leave null), but you can force a particular encoding
* to be returned, by setting this to 'gzip' or '' (no encoding)
*
* 'encodeLevel' : level of encoding compression (0 to 9, default 9)
*
* 'contentTypeCharset' : appended to the Content-Type header sent. Set to a falsey
* value to remove. (default 'utf-8')
*
* 'maxAge' : set this to the number of seconds the client should use its cache
* before revalidating with the server. This sets Cache-Control: max-age and the
* Expires header. Unlike the old 'setExpires' setting, this setting will NOT
* prevent conditional GETs. Note this has nothing to do with server-side caching.
*
* 'rewriteCssUris' : If true, serve() will automatically set the 'currentDir'
* minifier option to enable URI rewriting in CSS files (default true)
*
* 'bubbleCssImports' : If true, all @import declarations in combined CSS
* files will be move to the top. Note this may alter effective CSS values
* due to a change in order. (default false)
*
* 'debug' : set to true to minify all sources with the 'Lines' controller, which
* eases the debugging of combined files. This also prevents 304 responses.
* @see Minify_Lines::minify()
*
* 'minifiers' : to override Minify's default choice of minifier function for
* a particular content-type, specify your callback under the key of the
* content-type:
* <code>
* // call customCssMinifier($css) for all CSS minification
* $options['minifiers'][Minify::TYPE_CSS] = 'customCssMinifier';
*
* // don't minify Javascript at all
* $options['minifiers'][Minify::TYPE_JS] = '';
* </code>
*
* 'minifierOptions' : to send options to the minifier function, specify your options
* under the key of the content-type. E.g. To send the CSS minifier an option:
* <code>
* // give CSS minifier array('optionName' => 'optionValue') as 2nd argument
* $options['minifierOptions'][Minify::TYPE_CSS]['optionName'] = 'optionValue';
* </code>
*
* 'contentType' : (optional) this is only needed if your file extension is not
* js/css/html. The given content-type will be sent regardless of source file
* extension, so this should not be used in a Groups config with other
* Javascript/CSS files.
*
* Any controller options are documented in that controller's setupSources() method.
*
* @param mixed $controller instance of subclass of Minify_Controller_Base or string
* name of controller. E.g. 'Files'
