Add a new language support

If you would like to add support for language of your own choice to iNLTK, please start with checking/raising a issue here

Please checkout the steps I'd mentioned here for Telugu to begin with. They should be almost similar for other languages as well.

Improving models/using models for your own research

If you would like to take iNLTK's models and refine them with your own dataset or build your own custom models on top of it, please check out the repositories in the above table for the language of your choice. The repositories above contain links to datasets, pretrained models, classifiers and all of the code for that.

Add new functionality
