+ * @brief Namespace to host common utility methods.
+ *
+ * A method qualifies as a common utility function if,
+ * A)It is being used by the utility namespace at the same level as well as
+ * other files directly.
+ * B) The utility should be a leaf node and should not be dependent on any other
+ * utility.
