/**
* Converts HTML-formatted text into formatted PDF text.
*
* Notes:
* 2012-07-18
* Plugin relies on having browser, DOM around. The HTML is pushed into dom and traversed.
* Plugin relies on jQuery for CSS extraction.
* Targeting HTML output from Markdown templating, which is a very simple
* markup - div, span, em, strong, p. No br-based paragraph separation supported explicitly (but still may work.)
* Images, tables are NOT supported.
*
* @public
* @function
* @param HTML {String or DOM Element} HTML-formatted text, or pointer to DOM element that is to be rendered into PDF.
* @param x {Number} starting X coordinate in jsPDF instance's declared units.
* @param y {Number} starting Y coordinate in jsPDF instance's declared units.
* @param settings {Object} Additional / optional variables controlling parsing, rendering.
* @returns {Object} jsPDF instance
