+@Desc     : This module defines all codes, constants maintained globally \
+            and used across marvin and its test features.The main purpose \
+            is to maintain readability, maintain one common place for \
+            all codes used or reused across test features. It enhances \
+            maintainability and readability. Users just import statement \
+            to receive all the codes mentioned here. EX: Here, we define \
+            a code viz., ENABLED  with value "Enabled",then using \
+            this code in a sample feature say test_a.py as below. \
+
+            from marvinCodes import *
+            if obj.getvalue() == ENABLED
