Possible Interfaces
+++++++++++++++++++

  This analyzer lists classes that may be a base to create interfaces. 

Currently, classes with more than 1 defined method are used to identify possible interfaces. An interfaces are considered when at least 2 methods are common in 3 classes.

Only the name of the method is used to identify possible methods. Signature and method options are not taken into account.

.. code-block:: php
   
   <?php
   
   class a {
       function m1 () {}
       function m2 () {}
       function m3 () {}
   }
   
   class b {
       function m1 () {}
       function m2 () {}
       function m4 () {}
   }
   
   // This class has not enough shared methods with other classes
   class c {
       function m1 () {}
       function m4 () {}
       function m5 () {}
   }
   
   ?>
