A script that downloads git library code

Because of the daily build requirements, you need to download the code with a script to automate the compilation, which is a small piece of functionality throughout the system.

In the script, first determine if the GIT library exists and does not exist to clone the repository.

Otherwise, all changes are rolled back, then the pull operation is performed, and the final switch to the given branch.
