gcode development

Balanced trees are required for several tasks in MyNC. I've just written a graphics tool to debug them in three incarnations: for the kernel, for grelay and for mycpp. Fresh MyCpp::AvlTree code seems to work. Here's a screenshot of what is available at https://svn.sourceforge.net/svnroot/mync/trunk/mync-gtree.

Oh, and yes, I've registered MyNC at sf.net and have already imported several modules into SVN. The rest is due soon.
