// EulerAngles.icc - Inline methods for EulerAngles class.
//
// History:
//    9-Apr-1997  MF    Split off from original angles.hh.  Content-free.
//   26-Jan-1998  WEB   Fleshed out.
//   12-Mar-1998  WEB   Gave default constructor proper default values
//   13-Mar-1998  WEB   Simplified compare()
//   17-Jun-1998  WEB   Added namespace support
//   27-Jul-2000  MF    CLHEP version
