Get a specific item from a collection by ID (multi-part key)

[wabuMike]

The wiki says that getting a specific item by ID works with find: $person = $odataClient->from('People')->find('russellwhyte');

OData supports multi-part keys. This is also implemented (https://github.com/saintsystems/odata-client-php/blob/2474e87d30def0a3a985abc32af6a1d08cb6f83f/src/Query/Grammar.php#L160) and works great.

It took me a while to find that, which is why it would be great if we can document that. There are two documentations I recommend to improve:

1. Add alternative parameter data type "array" to https://github.com/saintsystems/odata-client-php/blob/2474e87d30def0a3a985abc32af6a1d08cb6f83f/src/Query/Builder.php#L767 . Like @param int|array $id

2. Add an example like the following to https://github.com/saintsystems/odata-client-php/wiki/Example-Calls :

   ##Get a specific item from a collection by multi-part ID
   
   // Or retrieve a specific entity by the Entity multi-part ID/Key
   // Issues an HTTP GET request to http://services.odata.org/V4/TripPinService/People('russellwhyte')
   $person = $odataClient->from('People')->find(['username' => 'russellwhyte', 'userid' => '1']);
   echo "Hello, I am $person->FirstName ";
