+ * @file symbolicNameTable.h
+ * @brief The symbolic name table maps a string name to a connection id
+ *
+ * When configuring tunnels/connections, the user provides a string name
+ * (symbolic name) that they will use to refer to that connection.  The symblic
+ * name table translates that symbolic name to a connection id.
