+Made fixes for HP compiler. All function parameter default values placed
+in .h file. Fixed the usual problem with HP comilers and the "for(Int_t i..."
+business. Replaced casting (Double_t [3][3]) to (Double_t (*)[3]) for HP.
+Lastly removed all "const" before function parameters which were 2 dim. arrays,
+because on HP root generates some strange code (?). Thanks Peter for the
+changes.

 New class for ITS coordiante transformations used by AliITSgeom nearly
 exclusively.
