Support for multiple faces

[adefalque]

Hi Nish,

Great sample thanks!
I'd like to add support for multiple faces but not sure how to tackle the problem.
I guess the idea would be to to remap recognized face rectangles from Microsoft Face Api to the Google detected faces. The thing is that the rectangle coordinates returned from MS Api does not match the ones returned by Google.
Any idea how to do this?

Thanks,
Alex
