-/**
- * Represents a pre or post processing filter on HTML Purifier's output
- *
- * Sometimes, a little ad-hoc fixing of HTML has to be done before
- * it gets sent through HTML Purifier: you can use filters to acheive
- * this effect. For instance, YouTube videos can be preserved using
- * this manner. You could have used a decorator for this task, but
- * PHP's support for them is not terribly robust, so we're going
- * to just loop through the filters.
- *
- * Filters should be exited first in, last out. If there are three filters,
- * named 1, 2 and 3, the order of execution should go 1->preFilter,
- * 2->preFilter, 3->preFilter, purify, 3->postFilter, 2->postFilter,
- * 1->postFilter.
- *
- * @note Methods are not declared abstract as it is perfectly legitimate
- *       for an implementation not to want anything to happen on a step
