- Centralize solver path resolution in Config.py - Add PATH-based discovery for GLPK and CBC on macOS/Linux - Preserve existing Windows behavior - Add environment variable overrides (MUIO_GLPK_PATH, MUIO_CBC_PATH) - Fix urllib3 version conflict in requirements.txt (compatible with botocore) This enables running MUIO from source on macOS/Linux and resolves dependency installation failure in a clean virtual environment.

Closes #10
Improve Cross-Platform Development Setup (macOS/Linux)
Overview
This PR addresses two issues encountered while attempting to run MUIO from source on macOS (Apple Silicon):
requirements.txtprevented clean installation in a fresh virtual environment.Together, these issues block cross-platform development workflows. This PR resolves both while preserving existing Windows behavior.
1. Cross-Platform Solver Path Resolution
Problem
OsemosysClass.pypreviously defined solver directories using OS-specific hard-coded paths for non-Windows systems (e.g.,glpk-4.65/w64,Cbc-2.10-osx10.15-x86_64-gcc9/bin).These paths:
Solution
Solver path resolution has been centralized in
Config.pywith the following priority:MUIO_GLPK_PATHMUIO_CBC_PATH
