 * Fix bug in getForwardingEntryFlags: Need to check all flags, not the first flag using "else if".
 
 Changes
+* http://redmine.named-data.net/issues/1085: In Name::Component, added comparison operators.
 * MetaInfo: Added setFinalBlockID for Name::Component, remove unused setFinalBlockID which take uint8_t*, etc.
 * Fix clang compiler warnings: Include headers, parentheses and cast explicitly.
 * Moved class ExcludeEntry to inner class Exclude::Entry.
