Plack::Middleware::Recursive - Allows PSGI apps to include or forward requests recursively

       Plack::Middleware::Recursive allows PSGI applications to recursively include or forward requests to other
       paths. Applications can make use of callbacks stored in "$env->{'plack.recursive.include'}" to include
       another path to get the response (whether it's an array ref or a code ref depending on your application),
       or throw an exception Plack::Recursive::ForwardRequest anywhere in the code to forward the current
       request (i.e. abort the current and redo the request).

       This middleware passes through unknown exceptions to the outside middleware stack, so if you use this
       middleware with other exception handlers such as Plack::Middleware::StackTrace or
       Plack::Middleware::HTTPExceptions, be sure to wrap this so Plack::Middleware::Recursive gets as inner as
       possible.

       The idea, code and interface are stolen from Rack::Recursive and paste.recursive.
