 To achieve the desired modularity we use the type of the sub-route as an argument to this top-level
 route constructor.
 
-We will build this route in `Common.Route` using a [Generalised Algebraic Data Type](http://dev.stephendiehl.com/hask/#gadts), or 'GADT'. Part of the reason for this is that it more providese more detailed type information for greater type-safety that aid in providing the guarantees that this package is built upon.
