Installs the specified plugin and any packages that it depends
                on. Installs the specified plugin and its dependencies in the
                local node_modules folder, adds it to the
                dependencies section in package.json,
                and prepares the plugin for all installed platforms. If you have
                not configured any platforms for the project, the NativeScript
                CLI will prepare the plugin when you add a platform.
