Quick Start for ProxyHiRes Fetcher

2. Create python virtual environment in a folder:
   • UNIX: python3 -m venv env
   • WINDOWS: py -m venv env
3. Activate Environment:
   • UNIX: source env/bin/activate
   • WINDOWS: .\env\Scripts\activate
4. Optional: python -m pip install --upgrade pip
5. Place copy.py file in directory
6. Run Script (within venv): python copy.py
7. Optional: To deactivate virtual environment; within the project directory type deactivate
