In my project, I nedd to implement a new resource api with subdirectory.
I failed use default function to do it. So I modify it.

Support resource route when function with subdirectory.
example: $routes->resource('Admin/Admins');

Looks good. Can you add a test for this to the RouterTest class?

Hi, @lonnieezell
When I run phpunit, it report Fatal error: Default value for parameters with a class type hint can only be NULL in C:\Tools\Wnmp\html\UT\system\Config\DotEnv.php on line 121.
Many developers meet this issure when their php version is lower than 7.
But my version is 7.0.8 .

check php -v on command line.
probably php versions are different between cli and web.

[takekoshinet]

my phpunit is passed.
php 7.0.0 on fedora25.
