"""
Authors: Armando, Lily, Eduardo, Gabe
Course: CST-205
Date: 05/14/2024
Summary: Runs a flask app that allows for the user to enter in a city name
and brings a second page with some weather information of that city currently.
GitHub Link: https://github.com/Wei-HaiMing/WeatherProject
=======
Gabe and Armando mostly worked on this python file
Armando: I worked on understanding the parameters that the API we used
and how to retrieve the correct information in order for city name
searches to function properly. Also retrieved and displayed weather
icon on the weather details page. I attempted to retrieve a map from the
API, but was unsuccessful.

Gabe: Coded app routes to each individual page. Took Armando's initial json and request code, and added functionality and test endpoints
for each individual data dump. Coded the form in home route such that it returned a string that was the user city search input.
Keying, API access and research in these aspects were done by Armando, and I built upon them by looking into json dumps and coding HTML
to display data from the requests. Added longitude and latitude data access directly for convenience.
