.register(installer_class, prio = 5) ⇒ Object
Register an Installer implementation. All Installer classes which wish to get picked automaticly using their ‘#match?` method have to register. Ad-hoc or small custom Installer meight not need to get registered, but need to get passed as an config option (`installer`)
Registration takes a priority which defines how specific the Installer matches a system. Low level installers, like “linux” or “bsd” use a small priority (2), while distribution installers use higher priority (5). Installers matching a specific version of a distribution should use heigher priority numbers.
