Installation tip

该 issue 报告了使用 ipy -X:Frames -m ensurepip 和可编辑 pip 安装来手动安装 IronPython PyPI 源代码分发包的路径。未确定目标文件或明确的文档变更；请验证这些命令是否仍然有效，并且只有在添加了经 maintainer 批准的安装说明后，才认为工作完成。

Hi guys, this is a really useful library - thankyou!

I just wanted to share with other users that to use it, I downloaded the Source Distribution from PyPi manually, extracted it, cd'd into its base folder, and then was able to install this using:

ipy -X:Frames -m ensurepip
ipy -X:Frames -m pip install -e (possibly also in an admin cmd, I can't remember)

As it happens, I've never been able to get IronPython 2.7 to install anything from PyPi, I get some /html5/ None + int TypeError or other).

But now, I happily managed to pass 18/23 of my tests after only 5 minutes or so tinkering - so thankyou ever so much! You've saved me from having to set everything up to use unittest!
