Added docstrings

Added docstring to models.py for the string method of the center model.  Also added further docstrings to the views.py
Created Stand model

Created a new Spatial Model that will hold produce stand data.  I migrated this model to the database and synced it.  I also validated the model in admin.py in order to be able to access it on the admin page.
Edited Stand model

Edited the fields of the stand model based on a how I plan on implementing adding the model to the database (based on a form registered users can access).  Changed around admin.py during an attempt at implementing another plan.  Changed it back to what it is now.  Also added a serializer in the first step of setting up the REST API.
