Issue:
Clarify the dependency requirements for Ubuntu 20.04+, which no longer contains Python 2.

Details:
User should be told to install the following applications before proceeding with QH installation:

• git
• gfortran
• python-is-python3

python-is-python3 will address the temporary issue of still issuing Python 2 commands, by linking them to the correct Python 3 interpreter.

Issue:
After downloading and installing quantum-honeycomp, there is the following error at execution:
bash: ../Downloads/quantum-honeycomp/psyrc/interpreter/../../bin/quantum-honeycomp: /usr/bin/python: bad interpreter: No such file or directory

Further Information:
OS: Ubuntu 18.04.3 LTS (fresh installation)
Aliasing python = python3 still allows for the installer to install, but running quantum-honeycomp will yield the error command not found. Directly executing the binary ./bin/quantum-honeycomp again results in command not found.

Issue:
When installing quantum-honeycomp following the instructions in the README, installer fails with the following:
File "../Downloads/quantum-honeycomp/pysrc/interpreter/pycommand.py", line 48, in install_dependencies
os.system(pip+" install "+l) # install this library
TypeError: unsupported operand type(s) for +: 'Nonetype' and 'str'

Additional info:

• OS: Ubuntu 20.04 LTS
• Updates: New virtual machine and all package updates applied
• It appears that you are calling pip using a method not recommended by the developer. See additional information here: https://pip.pypa.io/en/latest/user_guide/#using-pip-from-your-program.
• See additional info here: https://stackoverflow.com/questions/12332975/installing-python-module-within-code

Issue:
Filename "" is not a valid filename and will result in error on pulling from master on Windows-based systems.

Recommendation:
Rename to appropriate filename (valid characters, letters).

Severity:
Minor.

Issue:
Installer will show an error during installation of the multiprocessing module.

SyntaxError: Missing parentheses in call to 'print'. Did you mean print('Macros:')

Further Information:
Multiprocessing is built into Python since Python 2.6+ and is no longer needed. It could be safely removed unless otherwise needed for obsolete versions of Python (Python 2).
