This is for PHP package authors to require in their composer.json. It will
install their package to the correct location based on the specified package
type.
The goal of installers is to be a simple package type to install path map.
Users can also customize the install path per package and package authors
can modify the package name upon installing.
installers isn't intended on replacing all custom installers. If your package
requires special installation handling then by all means, create a custom
installer to handle it.
