Stage 7 of 7 for JetBrains Academy - Kotlin - Git Internals project.
The program allows the user to work with Git files with the following commands:
• list-branches - list the branches of a given directory, marking the current branch with a *
• cat-file - reads the content of a git object file ( requires the object's hash from the user )
• log - prints the log of the given branch ( it currently only follows the first parent, if a commit has more than one )
• commit-tree - prints out the full file tree of a given commit ( requires the object's hash from the user )
