* starting docs for pipelines

* working on an example

* clearing output

* starting to implement config changes and add documentation

* removing diff

* format

* templated pipeline notebook a bit

 #### Positional Encoding
 
-An extra trick is necessary to making the neural network expressive enough to represent fine details in the scene. The input coordinates $(x,y,z,\theta,\phi)$ need to be encoded to a higher dimensional space prior to being input into the network. You can learn more about encodings [here](../notebooks/visualize_encoders.ipynb).
