Composer introduction:

Composer is PHP5.3 or above Dependency management tools. It allows you to declare the code libraries your project depends on and it will install them for you in your project. Composer is not a package manager. Yes, it involves "packages" and "libraries", but it's managed on a per-project basis, with installations in some directory within your project (e.g. vendor). By default it won't install anything globally. So this is just a dependency management.
