+/**
+ * A collection represents a group of objects.
+ *
+ * Each object in the collection is of a specific, defined type.
+ *
+ * This is a direct implementation of `CollectionInterface`, provided for
+ * the sake of convenience.
+ *
+ * Example usage:
+ *
+ * ``` php
+ * $collection = new \Ramsey\Collection\Collection('My\\Foo');
+ * $collection->add(new \My\Foo());
+ * $collection->add(new \My\Foo());
+ *
+ * foreach ($collection as $foo) {
+ *     // Do something with $foo
+ * }
+ * ```
+ *
+ * It is preferable to subclass `AbstractCollection` to create your own typed
+ * collections. For example:
+ *
+ * ``` php
+ * namespace My\Foo;
+ *
+ * class FooCollection extends \Ramsey\Collection\AbstractCollection
+ * {
+ *     public function getType()
+ *     {
+ *         return 'My\\Foo';
+ *     }
+ * }
+ * ```
+ *
+ * And then use it similarly to the earlier example:
+ *
+ * ``` php
+ * $fooCollection = new \My\Foo\FooCollection();
+ * $fooCollection->add(new \My\Foo());
+ * $fooCollection->add(new \My\Foo());
+ *
+ * foreach ($fooCollection as $foo) {
+ *     // Do something with $foo
+ * }
+ * ```
+ *
+ * The benefit with this approach is that you may do type-checking on the
+ * collection object:
+ *
+ * ``` php
+ * if ($collection instanceof \My\Foo\FooCollection) {
+ *     // the collection is a collection of My\Foo objects
+ * }
+ * ```
