v2 api support

[robertwenquan]

Hi @soodoku

Sorry for the misuse of github issue; I am not sure how to reach out. This is Robert from Clarifai. Our api is at v2 that supports custom training, visual search, etc. Do you have any interest in following up? email me at robert@clarifai.com if you have interest. I hope we can make the best use of your current code base. Thanks for your contribution again~

Thanks,
Robert
