Updated routing.md

Through some debugging on the discord channel we found that Lumen does care about what you name your parameters whereas Laravel does not. It would be nice to have a notice in there so it is specified for those coming from Laravel and don't match up their parameter names with variables.

Simple test cases

Url: test/12/2/6/1983

$router->get('/test/{id}/{day}/{month}/{year}', function ($id,$day,$month,$year) {
    echo "$id - $day - $month - $year";
});

Return: 12 - 2 - 6 - 1983

versus

Url: test/12/2/6/1983

$router->get('/test/{anotherId}/{day}/{month}/{year}', function ($id,$day,$month,$year) {
    echo "$id - $day - $month - $year";
});

Return: 2 - 6 - 1983 - 12

Not sure how to word it as testing it; All your URL parameters either need to match up to the function, or none of them need to match up in order for it to work.

*this does not work

$router->get('/test/{one}/{day}/{three}/{four}', function ($id,$day,$month,$year) {
    echo "$id - $day - $month - $year";
});

*this does work

$router->get('/test/{one}/{two}/{three}/{four}', function ($id,$day,$month,$year) {
    echo "$id - $day - $month - $year";
});

I believe this is already noted in docs.

From reading the documentation (routing) there are a few points but nothing specific about naming the parameters correctly and mismatched parameter names.

It talks about how you cannot have dashes (-) in your parameters. And that the given parameters will be automatically inserted into the url in their correct positions (possible this is a good spot for the warning?) Required Parameters
