* \brief A map of ControlId to ControlRange

+ * The ControlInfoMap class describes controls supported by an object as an
+ * unsorted map of ControlId pointers to ControlRange instances. Unlike the
+ * standard std::unsorted_map<> class, it is designed the be immutable once
+ * constructed, and thus only exposes the read accessors of the

+ *
+ * In addition to the features of the standard unsorted map, this class also
+ * provides access to the mapped elements using numerical ID keys. It maintains

+ * through the idmap() method to help construction of ControlList instances.
