- * Description: part of STAR HBT Framework: AliFemtoMaker package
- *   a simple Q-invariant correlation function           
- *
- ***************************************************************************
- *
- * $Log$
- * Revision 1.1.1.1  2007/04/25 15:38:41  panos
- * Importing the HBT code dir
- *
- * Revision 1.1.1.1  2007/03/07 10:14:49  mchojnacki
- * First version on CVS
- *
- * Revision 1.4  2000/01/25 17:34:45  laue
- * I. In order to run the stand alone version of the AliFemtoMaker the following
- * changes have been done:
- * a) all ClassDefs and ClassImps have been put into #ifdef __ROOT__ statements
- * b) unnecessary includes of StMaker.h have been removed
- * c) the subdirectory AliFemtoMaker/doc/Make has been created including everything
- * needed for the stand alone version
- *
- * II. To reduce the amount of compiler warning
- * a) some variables have been type casted
- * b) some destructors have been declared as virtual
- *
- * Revision 1.3  1999/07/29 02:47:09  lisa
- * 1) add OpeningAngle correlation function 2) add AliFemtoMcEventReader 3) make histos in CorrFctns do errors correctly
- *
- * Revision 1.2  1999/07/06 22:33:20  lisa
- * Adjusted all to work in pro and new - dev itself is broken
- *
- * Revision 1.1.1.1  1999/06/29 16:02:57  lisa
- * Installation of AliFemtoMaker
