+    .Description
+    Assume there is a problem which can be solved by different algorithms.
+    Then you can write multiple classes to approach this problem. +
+    Now if you want to decide which algorithm to use in runtime, you can just
+    approach this case by a simple way:
+
+   * Let all the problem-solving classes inherit from
+   `class ImplementInterface<T>` , and call the constructure with giving
+   `identify` (type `T` ) .
+   * Create an object, type `RegisterInterface<T>` , and register all your
+   implement class to it by call `regImplement(pointer to the class)`.
+   * Select which implement class you want by call `getImplement(identify)` ,
+   which will return the pointer to the corresponding class.
