 * This module makes its instances non-copyable, by explicitely disabling its initialize_copy method.
 *
 * To create a non-copyable class, simply include the SFML::NonCopyable module.
 *
 * Usage example:
 *
 *   class MyNonCopyableClass
 *     include SFML::NonCopyable
 *     ...
 *   end
 
 * Deciding whether the instances of a class can be copied or not is a very important design choice. You are strongly 
 * encouraged to think about it before writing a class, and to use SFML::NonCopyable when necessary to prevent many 
 * potential future errors when using it. This is also a very important indication to users of your class.
