Project: Variant Satisfiability Algorithm in Maude
Details: Implements the variant satisfiability as sketched
         in the paper, "Metalevel Algorithms for Variant Satisfiability."
         For a primer on the Maude language, see the Maude manual,
         available at:

         > http://maude.cs.illinois.edu/w/index.php?title=Maude_Manual_and_Examples 

         Pay particular attention in the Manual to sections:

         > Reflection, Metalevel Computation, and Strategies
         > Unification and Variant Generation

         As we make heavy use of these facilities in the code.
         To see how to run the code, check the file:

         > run.maude

         or any of the files in the /examples directory. Any
         example can be run by running the Maude interpreter 
         (2.7 or later, though Alpha 108 is recommended), by 
         first changing to the /examples directory and then
         typing:

         > maude [examplefile].maude

         where [examplefile] is the name of the example file
