upgrades on MOM SSC classes, introduction text

To several of the ruby MOM Simple Set Core classes, I added a demo program which aimed at showing the respect class works/aimed at crashing if there's a bug. Well, actually, the demo programs shall call each method with any possible value (including invalid ones). If the program runs trough, everything is okay; if it doesn't, that means homework, i.e. the class needs to be fixed. Yet a few days ago, I uploaded the upgraded classes to the MOM SSC repository (changelog).

I didn't change the version number, since the moment I want to do this, is when MOMnet.rb is completed also. -- That equals the moment, when all the classes using MOMnetNode and MOMnetConnection work.


Additionally, I took the time to improve (well, actually, replace) the description the goals of the MOM SSC project. I hope, now any passer-by can figure out the idea quite easy.
