+* @brief
+*  This file contains function declaration and structures for rate control
+*  memtabs
+*
+* @author
+*  ittiam
+*
+* @remarks
+*  The rate control library is a global library across various codecs. It
+*  anticipates certain structures definitions. Those definitions are to be
+*  imported from global workspace. Instead of that, the structures needed for
+*  rc library are copied in to this file and exported to rc library. If the
+*  structures / enums / ... in the global workspace change, this file also needs
+*  to be modified accordingly.
