+0.60 2009-10-08 - modified \psPrintValue to allow algebraic function mode
+ - fix bug with algebraic=true for all macros with \psplot
+ which need postfix code
0.59 2009-01-23 - add option \psk@xShift for \psPrintValue
0.58 2008-12-08 - add the ChebyshevT and ChebyshevU (first and second kind)
the macros are only wrappers for the PS routines
