ZXingWidget does not compile

[tbissonnette]

Downloaded the latest version, and ZXingWidget does not compile. Generates an error that it cannot allocate an object of abstract type on this line of Decoder.mm:

Ref source (new GrayBytesMonochromeBitmapSource(subsetData, subsetWidth, subsetHeight, subsetBytesPerRow));

There is no concrete implementation of LuminanceSource::getRow in the GrayBytesMonochromeBitmapSource child class.

Thoughts?

To clarify, it is the master branch that does not compile. Had better luck with the ios4 branch ;)
