Initial whack at a new EQ effect for Modulex...  I think it's mostly working,
minus the UI bit doesn't exist yet...
Better default frequencies...
version 1.0 of the UI widget... Still more work to be done...
Now it starts to become pretty f'ing sweet...
More refinement...  Merging now, I'll work on making the points
movable with the mouse later...
Even more refinement...
