+`Interpreter`__
+============
+
+Purpose
+-------
+
+For a given language, it defines the representation of its grammar as
+"No Terminal Expression" and "Terminal Expression",
+as well as an interpreter for the sentences of that language.
+
+Examples
+--------
+
+-  An example of a binary logic interpreter, each definition is defined by its own class
