New FAQ and new tutorials

The new GeneXproTools FAQ was compiled from support requests received over the years, and covers Installation Issues and Demo Functionality, Classification and General Issues, plus Algorithms and Evolution Issues. Thanks to everyone who contributed!

Three new tutorials:

1. DNA Microarrays: A Case Study
2. What is GEP?
3. Karva Notation: The Native Language of GeneXproTools

These new tutorials are the first three of what I hope will grow into an interesting forum not only to discuss practical and theoretical matters but also for talking about different uses of GeneXproTools. There are people around the world using GeneXproTools to study amazing things (from top quark and Higgs analysis to new drugs and analog circuits) and it would be great to have them using this forum to talk about their work and what they are achieving with GeneXproTools (I encourage and invite you to submit your contributions to me personally).
