#This file loads  different apps on different urls 
'''
THIS IS THE FILE THAT KINKS UP ALL THE INDIVIDUAL PAGES 
It is worth noting that in both of these project structures, the Dash instance is defined in a separate app.py, while the entry point for running the app is index.py. 
This separation is required to avoid circular imports: the files containing the callback definitions require access to the Dash app instance however if this were
imported from index.py, the initial loading of index.py would ultimately require itself to be already imported, which cannot be satisfied.
