HighestPowerGenericDegrees( W )
returns a list holding the A-function for all irreducible characters of
the Coxeter group W, that is, for each character chi, the degree of
the generic degree of chi (in the one-parameter Iwahori-Hecke algebra
Hecke(W,X(Rationals)) corresponding to W). The ordering of the
result corresponds to the ordering of the characters in CharTable(W).
