Current CDN Example Not Working #81

Description

Hi. I'm trying to conduct a very simple test using just a single HTML file and by including the tesseract.js script using the CDN source in the documentation:

<script src='https://cdn.rawgit.com/naptha/tesseract.js/1.0.10/dist/tesseract.js'></script>

My HTML file is simple:

<html>
    <head>
        <script src='https://cdn.rawgit.com/naptha/tesseract.js/1.0.10/dist/tesseract.js'></script>
        <title>Tesseract Test</title>
    </head>
    <body>
        <label for="fileInput">Choose File to OCR:</label>
        <input type="file" id="fileInput" name="fileInput"/>
        <br />
        <br />
        <div id="document-content">
        </div>
    </body>
    <script>
        document.addEventListener('DOMContentLoaded', function(){
            var fileInput = document.getElementById('fileInput');
            fileInput.addEventListener('change', handleInputChange);
        });

        function handleInputChange(event){
            var input = event.target;
            var file = input.files[0];
            console.log(file);
            Tesseract.recognize(file)
                .progress(function(message){
                    console.log(message);
                })
                .then(function(result){
                    var contentArea = document.getElementById('document-content');
                    console.log(result);
                })
                .catch(function(err){
                    console.error(err);
                });
        }
    </script>
</html>

But if I try to add an image, nothing happens in the console or anywhere else. This is also true if I clone the repository and instead load tesseract.js from the dist directory.

I see that the main (non-github) website for the project uses the CDN version 1.0.7, so I tried using that source instead. It came to life and started reporting back progress, but then threw the following error:

tesseract_example.html:27 Object {status: "loading tesseract core", progress: 0}
tesseract_example.html:27 Object {status: "loading tesseract core", progress: 1}
tesseract_example.html:27 Object {status: "initializing tesseract", progress: 0}
index.js:10 pre-main prep time: 65 ms
tesseract_example.html:27 Object {status: "initializing tesseract", progress: 1}
worker.js:11953 Uncaught DOMException: Failed to execute 'postMessage' on 'DedicatedWorkerGlobalScope': An object could not be cloned.()

respond	@	worker.js:12185

Am I just doing this wrong somehow?
