PSR-4 is case sensitive. The structure has to be
app/Helpers/Router.php or better App with capital A.
All class names MUST be referenced in a case-sensitive fashion.
The subdirectory name MUST match the case of the sub-namespace names.
The terminating class name corresponds to a file name ending in .php. The file name MUST match the case of the terminating class name.
