Adding FGL to the hierarchical libraries

Hi there, Abe Egnor and Isaac Jones at Aetion Technologies have refactored the modules of the FGL (http://eecs.oregonstate.edu/~erwig/fgl/haskell/) into the new hierarchical name space. It is therefore possible now to add the FGL directly to the hierarchical library structure. I don't really know how that works, but I would like to contribute the FGL to the hierarchical libraries. (I haven't released the new version yet, but plan to do so soon.) I have attached the modules to this email. If you want to add them, please go ahead. If you have any questions, please let me know. Thanks, Martin
