Added some installation examples using Conda

I thought this could be useful info for neophytes like me. I tested the commands an all of them work.

A mistake. I used "--name myenv" in all cases. I checked again and it works.

Do you mean "it works" as described in this pull request and we should merge it? Or "it works" with --name myenv? If the latter please fix the pull request.

Sorry for the confusion. The installation works when following the instructions in the fixed pull request.

Okay, thanks!
