Source code manager like Git.

The main goal of this project is to show how a source code manager works in as little code as possible.

The others goals are

1. Keep the code very modular.
2. Avoid Memory leaks/corruption during development phase by using valgrind tool.
3. Keep the code very simple and easy to understand.

Currently supported commands are

1. init. => Initialize a new repo.
2. checkout => Checkout files or a branch.
3. branch => Create a new branch.
4. status => Show thats files that have changed.
5. ls => Show the list of files under revision control.
6. commit => Commit the changes.
7. rm => delete a files from revision control.
8. sha => Print the SHA id of the file.
