Figure out what to where we can use Hongwei's great file upload code.

Example html:

<tr>
    <td>Upload file</td>
    <td>SCADA file (.csv) 
        <input type='file' name='scadaFile' class='scadaFile' accept='.csv' onchange='handle_files(this.files)'>
        <input type='hidden' class='hiddenScadaFile'>
    </td>
</tr>

Then:

function handle_files(files) {
    // read file to a hidden input field
    reader = new FileReader();
    reader.readAsText(files[0]);
    reader.onload = loaded;
    function loaded(evt){
        evt.target.result;
        document.getElementsByClassName('hiddenScadaFile').value = reader.result;
    }
}

I am digging it. Actually, my previous upload file method is not that secure enough. I also need to check the security of uploading file data.

Hmm, actually let's move this out of the Q2 event and think about it once we've got a better issue list for Q2.
