[chicolucio]

Describe the bug

streamlit-ph script does not work.

2. run streamlit-ph on terminal
3. message: Error: Invalid value: File does not exist: Home.py

Expected behavior Browser window opens with Streamlit app

Screenshots NA

Specification

• pH-diagrams version: 0.3.2
• Python version: 3.10
• platform: Linux (but will happen in all platforms)

Additional context The file is not part of the package. Maybe the project should be restructured in a way that the Streamlit app becomes a module.

I'm dropping for now the idea of shipping the Streamlit app together with the package:

• it is just a visualization tool, with limited use since made for educational purposes. With the package, one has more options.
• the Streamlit app has issues with entry-points (https://togithub.com/streamlit/streamlit/issues/4162) that make things too difficult

Added this in the README:

A local version of the Streamlit app can be used cloning the repo and running streamlit run Home.py on a terminal. A browser window will open (if not, follow the instructions shown on the terminal output).

This way, one can use the Streamlit app locally as long as a proper virtual environment is set.
