Algorithm for counting nonisomorphic colorings

[David Wilson]

Tsvetelina Petkova has asked for my help with a program to count nonisomorphic 
colorings of general graphs.  I haven't made any promises.  I can describe an 
algorithm for doing this, however, it would be a bear to program in Perl or C++, 
which are all I have at my disposal.  I was wondering if someone versed in Mma 
or some other symbolic language might want to discuss the possibility of 
implementing my algorithm.
