AMPL on Streamlit

Since AMPL and all Solvers are now available as Python Packages. To use them in streamlit you just need to list the modules in the requirements.txt file as follows:

--index-url https://pypi.ampl.com # AMPL's Python Package Index
--extra-index-url https://pypi.org/simple
ampl_module_base # AMPL
ampl_module_highs # HiGHS solver
ampl_module_gurobi # Gurobi solver
amplpy # Python API for AMPL

and load them in streamlit_app.py:

from amplpy import AMPL
ampl = AMPL()
