handle the case where a parent controller is configured at '/' when adding a subController.
Merge pull request #18 from urkle/fixSubControlerWithSlashParent

adding a subcontroller when parent is set to / doesn't work.
Support unnamed methods in Auto-Collection

Example:
class User
{
    get()
    {
        // List all users..
    }

    post($data)
    {
        // Create user...
    }
}
add in tests for "root" methods.
