+Includes methods to work with network addresses.

+#### Base address methods
+
+Different operations with address parts:
+
+* `scheme`
+* `user`
+* `password`
+* `host`
+* `protocol`
+* `path`
+* `query`
+* `fragment`
+
+#### Address conversion from relative to absolute format

 $address = new \Yggverse\Net\Address(
-    'http://yo.ygg'
+    '/a2'
 );
 
 var_dump(
-    $address->getScheme() // Scheme substring
