## Usage
var EPub = require("epub");
var epub = new EPub(epubfile, imagewebroot, chapterwebroot);
Where
* **epubfile** is the file path to an EPUB file
* **imagewebroot** is the prefix for image URL's. If it's */images/* then the actual URL is going to be */images/IMG_ID/IMG_FILENAME*, `IMG_ID` can be used to fetch the image form the ebook with `getImage`
* **chapterwebroot** is the prefix for chapter URL's. If it's */chapter/* then the actual URL is going to be */chapters/CHAPTER_ID/CHAPTER_FILENAME*, `CHAPTER_ID` can be used to fetch the image form the ebook with `getChapter`
* **imagewebroot** is the prefix for image URL's. If it's */images/* then the actual URL (inside chapter HTML `<img>` blocks) is going to be */images/IMG_ID/IMG_FILENAME*, `IMG_ID` can be used to fetch the image form the ebook with `getImage`
* **chapterwebroot** is the prefix for chapter URL's. If it's */chapter/* then the actual URL (inside chapter HTML `<a>` links) is going to be */chapters/CHAPTER_ID/CHAPTER_FILENAME*, `CHAPTER_ID` can be used to fetch the image form the ebook with `getChapter`
Before the contents of the ebook can be read, it must be opened (`EPub` is an `EventEmitter`).
