Tensorflow conditionals and while loops

Recntly I found myself needing to implement more advanced control flow in some models I have been hacking on in my free time. In past I never really needed any graph conditionals or loops or any combinations thereof, so I had to dive into documentation and read up on them.

This blog post covers tf.cond and tf.while_loop control flow operations and was written to document and share my experience learning about them. Both of the operations seem intuitive on the first look, but I got bitten by them so I wanted to document their usage on practical examples so I have something as a reference I can return to in the future should I need to.
