The default now, to use the official Python.org installers, can be disruptive to users that have the same Python version already installed on their system as it uninstalls that pre-existing version. Also makes it difficult/impossible to have multiple copies of the IfcOpenShell build system on the same system. There doesn't seem to be another way to get official Python binaries (except for say portablepython and the like), so the only alternative seems to be to build from source. This is what the *nix build system does now.

@Stinkfist0 is this observation correct? thoughts?
