Development Process: Introduction for the Conda

[YankeMao]

We are going to expand the introduction of the Conda, which is a very helpful tool for managing the environment, project, etc. Besides the existing content, we will focus on expanding the introduction of the Conda, the difference between MiniConda and Anaconda, and the setup of the Conda. In addition, we will add an intruction to installing the Anaconda on MacOS and Windows and nine types of major tasks that Conda can work on which include the most commonly used command of Conda.

[YankeMao]

I will focus on writing instructions for four types of tasks, including Managing conda, Managing environments, Managing channels, and Managing packages.

I will focus on installing anaconda on windows and macos. As well as do some restructuring for the existing setup_conda.md

I will focus on writing conda manging in python, virtual packages, creating custom channels, projects and viewing command -line help.
