Document Reorganization

[xusine]

This is the suggestion from Mark.

It would be good to divide the documentation into a README file which describes simply how to run the benchmark, and a more detailed document (perhaps a PDF) with the architecture of the load generator, how to run an experiment, and how to set various parameters to create certain scenarios. This would give more structure to each file (i.e., the README which is visible by default just explains the architecture of the benchmark and how to run it, and then more details are available for those who are curious to tune it).

Maybe a better way for organizing all the document is to have a standalone web site subordinated by the cloudsuite.ch. We can use the same template used by the Linux kernel documentation.
