"pylink" name is used by another python module

[ProposeleSS]

There is another python module called 'pylink' and when installing pylink-square via pip, the first one is overwritten. I think it would be a good idea to change module name to something like 'pylink-square'

Sorry about the delay here, been a busy few weeks. This has been raised before. I think changing the module name would be a large change (requiring all users to update their code), so if I we were to do it, it would be better as a major change. This has been raised before though, and I think something like an alias might be useful (e.g. pylink_square, pys, pyls or something similar). I gthink doing it across two major versions could work: having one introduce an alias with a deprecation warning, then the second one removing the old link. Thoughts? It wouldn't be an immediate change.
