------------------------------------------------------------

I got it to read files.  I installed VS 2012 Express and installed the latest Cordova 3.4
package.  Next, I transferred all my source code into Visual Studio project based on the WP8
project template.  Still, after building the project in VS2012 and running it on my Nokia
phone, the same error occurred.  So I set several breakpoints in file.cs.  I noticed the readDataUrl
method was implemented, but the others are not yet, so I tested it.  I discovered the FileEntry
method breakpoints were getting hit, but the readAsDataURL method was never called.  So I
moved up into the FileReader.js and added some console.logs.  Suddenly, the next time I ran
it the debug breakpoint in the readAsDataURL method of file.cs was hit, weird. So,something
was going on with javascript, but I don't know what.  It has worked fine ever since. 

One thing I don't understand is how the browser knows to call the Cordova FileReader methods
instead of the HTML5 FileReader methods?

> The getFile fileEntry object comes back OK, except the values of fullPath, toNativeUrl
and toURL are identical.  I already reported that.  However, the fileEntry.isFile says "true"
so I assumed something was there.  However when I pass that fileEntry into a FileReader object
and try to use reader to read the file I get the following results:
> reader.readAsArrayBuffer and reader.readAsDataURL both throw a TYPE_MISMATCH_ERR.  I
saw in the docs that readAsArrayBuffer is not supported on WP8, but I figured I'd try it anyway.
> I got an error message on reader.readAsBinaryString saying that method is missing.  I'm
not surprised about that since the HTML spec says it is deprecated anyway.
> I also got a fileEntry back from window.resolveLocalFileSystemURI (had to put '///' in
front of the folder and file name to get it to work) and tried to use that.  It gave the same
results.
